How does a Bollinger engine work?
The engine is a 2 stroke 'semi' diesel. Inlet and exhaust are as per 'normal' two stroke diesel but the injected fuel is not ignited by compression alone as in a normal diesel. Instead a 'hot bulb' on the cylinder head is heated with a blow-lamp before starting and heat from this, transferred to a tube in the combustion chamber which ignites the fuel to start the engine. Once running the engine itself maintains the temperature. Often called a Hot Bulb Engine.
How does an engine starter works?
Inside the engine you have pistons attached to rods that are attached with bearings to the crankshaft. The crankshaft has offset points where the rods attach. The pistons are housed in cylinders and on top of the cylinder you have what is called a head. Inside the head are valves that let a fuel and air mixture into the cylinder. The valves are operated by the camshaft which is somehow geared to the crankshaft. As the piston moves up in the cylinder during the compression stroke, the fuel/air is compressed and a spark then ignites the mixture driving the piston down which turns the crankshaft causing one of the other pistons to go up compressing the gas in that cylinder. When this explosion occurs, the piston gets slammed down. That is the power stroke. That causes the crankshaft to turn, sending power to the transmission which in turn allows the car to move. Then the piston returns because of the momentum of the flywheel and the force of the other pistons if there are any. At the same time, a valve opens allowing the burned fuel air mixture to leave the cylinder and flow through the muffler and out the tailpipe. That is the exhaust stroke. Then the exhaust valve closes as the intake valve opens, allowing new fuel mixture to get sucked in during the intake stroke. Then the compression stroke outlined above repeats the entire cycle. That is pretty basic but it should give you an idea of how it all works. Below are some of the common variations of this. A diesel engine works similarly, but the detonation is caused by compression rather than ignition. Instead of spark plugs, it is the pressure inside the cylinder which causes the fuel mixture to explode. Fuel injection is required to get the amount of pressure necessary for detonation to occur. Glow plugs are only needed to warm the engine for starting, and a larger starter, battery, and alternator may be required. The cylinder walls might also be thicker. Otherwise the process works pretty much the same as for a 4-stroke gasoline engine. Then there is the rare Wankel engine that Mazda once used. It contains one or more rotors that have 3 surfaces. There is a rod called an eccentric that functions similarly to the valves of a 4-stroke reciprocating engine. However, a rotary engine is technically a 2-stroke engine since every rotor surface fires once per revolution of the crankshaft, while in a 4-stroke reciprocating engine, the cylinder only fires every other rotation. Anyway, the spark plugs fire and the explosion causes the rotor to rotate, sending the power to the transmission and wheels. Then as the rotor turns the eccentric opens the exhaust port to let the exhaust out and opens the intake port to allow new fuel mixture inside, readying the rotor to fire again once that same surface reaches the same location. The other surfaces fire while the first surface is readied to fire again. In 2-stroke engines such as in some motorcycles and yard equipment, the pistons also double as valves and both sides of the pistons are involved. So that means that the fuel requires a lubricant to be added since the fuel passes through the crankcase. While the piston is in the power stroke, new fuel air mixture is sucked into the crankcase for the next power stroke. Then ignition occurs, the piston is forced down as part of the power stroke and then the exhaust and intake ports are cleared. As the downward stroke forces new fuel-air-lubricant mixture into the cylinder, the exhaust is cleared, and the piston is again in the compression stroke.
How does an MPFI engine work?
Asnwer:MPFI stands for Multi Port Fuel Injection. As opposed to TBI, Throttle Body Injection. A cam and crank sensor tell the engine controller which cylinder's injector to fire and for how long. They fire with the same time as the spark plugs do. This is a more fuel efficient way to gain power. The TBI system has one or more injectors that spray fuel into the throttle body and the mixture is drawn into the engine all at once. The MPFI system has one injector per cylinder and only sprays on the compression stroke. Answer:mpfi in automobile engine is an system used in diesel engines to spray diesel at a higher speed so as to ignite the charge of air which is compressed at a higher temprature in this there are diferrent injectors on each cylinder head to give higher efficency of fuel burning this is mpfi system in automobile engines.
How calculate the engine work from pressure crank-angle diagram?
Well Work is the integral of P*dV and since the crank angle plot doesn't directly show volume you need to calculate instaneous volume of the cylinder as a function of crank angle. If you know the bore and stroke you can find the volume of the cylinder and you can relate this to the crank angle. Once you have these values you can replace the crank angle with volume and have a P-V plot or pressure on the y-axis and volume on the x-axis. Then you can integrate the area under the curve and find the work from the engine. However, all this is done for you if you can find the P-V diagram for your engine or engine cycle (Sterling, Atkinson, Otto, Diesel, etc.) and integrate this for the work.
Why diesel engine is called compression ignition engine?
A compression ignition engine works with Pistons and Valve openings. There is an intake valve, with lets the fuel and air into the cylinder, and the exhaust valve which allows for the escape of the combustion. The engine starter, supposedly started by a battery, gives the piston an Initial movement away from the valves, which bring the fuel and air into the cylinder, then pushes the piston back up, with this mixture of fuel, which is at a certain mixture which is then ignited by a spark plug. The explosion throws the piston back down which releases the exhaust valve allowing for the exhaust to exit. Once the exhaust leaves the piston moves back up , probably by the flywheel... and is brought down again which allows another mixture of fuel. This allows the engine to begin on its own timing without the need of a starter.
Why does a four stroke engine run cooler than a 2 stroke engine?
A four-stroke engine runs cooler than a two-stroke engine primarily because it has a more efficient cooling system due to its longer cycle, which allows for more complete combustion and better heat dissipation. In a four-stroke engine, the intake, compression, power, and exhaust strokes are separated, giving more time for heat to escape during the exhaust stroke. In contrast, a two-stroke engine fires once every revolution, leading to less time for heat to dissipate and often resulting in higher operating temperatures. Additionally, two-stroke engines typically mix oil with fuel for lubrication, which can also contribute to increased heat generation.
What are cubic inches in an engine?
Cubic inches is the total volume of all cylinders. If you wanted to know the cubic inches of a particular engine you would measure the diameter of the cylinder bore and the stroke of the crankshaft, then use your calculator to figure out the total volume. The formula for the area of a circle is pi times the radius squared. The formula for the volume of a cylinder is area of the circle times length (stroke) of the cylinder. Once you have the volume of the cylinder you can multiply that number by the number of cylinders for total volume (displacement).
Why not diesel engine is spark ignited?
A gasoline injects fuel into the cylinder as it is filled with air, compresses it, then ignites the spark plug to trigger the power stroke. In a diesel engine air is compressed up to 3 times more causing a much higher cylinder temp. Once the air in the cylinder is hot diesel fuel is injected directly into the cylinder and is ignited by the high temperature.
What is meant by the term 'the engine firing interval'?
Its a scary term at first but its easy to understand once you get the knack for it. An engine that has a 270 degree firing order means the bangs (power stroke) from each cylinder are 270 degrees of crankshaft rotation appart. When cylinder one fires, cylinder two will fire 270 degrees later, this trend would continue if the engine had more cylinders i.e. 4,6,8,10, and 12 cylinder engines. If and engine had a 360 degree firing interval its the same as above, cylinder one goes bang, cylinder two goes bang 360 crankshaft degrees later. Hope this helps. Its a scary term but its easy once you get the knack of it. Firing interval means the degrees in crankshaft rotation the power strokes are appart in an engine. Take for example the engine in the 2008 Triumph Scrambler it is a twin cylinder engine with a firing interval of 270 degrees. In this engine when cylinder one goes on its power stroke, cylinder two will have its power stroke 270 crankshaft degrees later. Ok now lets take the Cheverolet Corvette, Chevy has the firing interval at 90 degrees. So that means cylinder one fires then cylinder 8,4,3,6,5,7,2 follow all 90 degrees appart from each other. Hope this helps
How many cylinders fire at once on a 4 cylinder engine?
1 cylinder at a time.
Which cars come standard with a 3 cylinder engine?
There are now not many cars in the United States that are made with a 3 cylinder engine. A couple of the vehicles that were once made with a 3 cylinder engine is a Geo Metro and Dihatsu Charade.
Will the dodge charger turns off if theres no oil?
Eventually, yes. Once the engine ceases from lack of lubrication. There is no safety devise to prevent engine damage if that is what you are asking.

What is the difference between two and four stroke engines?
In a 4-stroke engine, the steps (strokes) are:Intake stroke: During the intake stroke, the piston goes down from the top of the cylinder to the bottom, reducing the pressure inside the cylinder. It then draws a mixture of fuel and air into the cylinder through the intake port, ready for the compression stroke.Compression stroke: With both intake and exhaust valves closed, the piston goes back up to the top of the cylinder compressing the fuel-air mixture. This is what happens during the compression stroke.Power stroke: The compressed air-fuel mixture is then ignited by a spark. The pressure from the fuel-air mixture combustion drives the piston back down with humongous force, keeping the crankshaft turning. This is the power stroke phase, which is the main source of the engine's torque and power.Exhaust stroke: Finally, during the exhaust stroke, the piston again goes up and pushes the burned gas from the cylinder out the exhaust valve.Something worth mentioning is that the spark plug only fires once every two revolutions in a 4-stroke engine. Unlike the four stroke one, a two stroke engine has three strokes combined into one action, meaning the intake and exhaust are both integrated into the compression movement of the piston, therefore eliminating the need for valves. This is thanks to an inlet and exhaust port integrated into the wall of the combustion chamber.As the piston goes down from combustion, spent gasses are allowed to exit the chamber through the exhaust port. The air-fuel mixture is drawn through an inlet located lower in the chamber. As the piston rises again, it blocks off the inlet and exhaust ports, compressing the gasses at the top of the chamber. The spark plug fires and the process starts over.The spark plug fires on every revolution.=====A two stroke engine can produce twice the amount of power (and makes twice as much noise) than a four stroke engine of the same size. This is because it fires once every revolution, giving it twice the power of a four stroke, which only fires once every other revolution. Significantly, it also has a higher weight-to-power ratio because it is much lighter.Two stroke engines are simpler and cheaper to manufacture compared to four stroke engines because of their simpler design. Four stroke engines are longer lasting than two stroke engines that don't have a dedicated lubricating system. However, the spark plugs in a two stroke engine last longer than those in a four stroke engine.Four stroke engines are more fuel efficient and environmentally friendly when compared to two stroke engines that also create an unpleasant smell. Two stroke engines are responsible for much more pollution due to the combustion of the oil that has to be added to the fuel to lubricate the piston.
Type of internal combustion engine?
diesel
How many times does a 2 stoke engine fire per revolution?
A 2-stroke engine fires once per revolution of the crankshaft. This is because the engine completes a power stroke with every rotation, utilizing both the intake and compression strokes in a single revolution. This design allows for a simpler and lighter engine, but it also results in less efficient fuel consumption and higher emissions compared to 4-stroke engines, which fire once every two revolutions.
Where should the rotor be pointing when the 1 cylinder is at top dead center on a 1987 ford ranger 2.9liter v6 engine?
It really doesn't matter where it points as long as it's pointing at the post on the distributor that has the number one wire on it. Just remember, that's a 50/50 chance. It could be 180 degrees out of time. At TDC, the rotor should be pointing toward the position where the number 1 spark plug wire plugs into. If the rotor is pointing in the opposite direction you need to rotate the engine once more since the engine rotates twice, once on the compression stroke (TDC) and once on the exhaust stroke (not TDC).
