The fuel rail.
Engines with Port Fuel Injection have fuel lines that run from the pump (in the tank) to the engine. Once the fuel lines get to the engine, they connect to the fuel rail, which is pressure regulated to ensure that each fuel injector gets the correct amount of fuel. The injectors are apart of the fuel rail, and spray fuel into the intake air stream of each cylinder.
Internal engine has its energy ignited in the cylinder. like 99.9% of engines today An external combustion example is a steam engine where the heating prosses is done in an boiler out side the engine.
because energy sourse(pressurised steam) is created externally (in boiler) prior to delivery to piston cylinder
External Combustion engine is an engine in which combustion of fuel takes place outside the cylinder. e.g.Coal fired steam engines in trains
Internal combustion engine is where the fuel is ignited in the cylinder to make the piston move, petrol or diesel. A steam engine has an external pressure vessel to supply the steam to the cylinder to push the piston. the is no combustion in the engine as such.
The 4 cylinder Saturn engines used an "Oil bath" timing chain. The V6 Saturn engines used an "external" timing belt.
Internal combustion engines burn fuel inside the engine to generate power, while external combustion engines burn fuel outside the engine and use the resulting heat to create power, such as in steam engines. Internal combustion engines are more common in vehicles due to their compact size and efficiency, while external combustion engines are used in specific applications like power plants and some marine propulsion systems.
In terms of engines, an external combustion engine such as a steam engine burns fuel outside of the pressure cylinder used to drive the piston. An internal combustion engine such as a petrol or diesel engine burns the fuel inside the pressure cylinder used to drive the piston.
The term "Internal combustion" means the burning, or combustion of the fuel/air is detonated in an enclosed cylinder under compression, driving piston down. If the combustion was external, there would simply be an explosion in the air that produces no power.
A car engine can be classified based on the number of cylinders it has. It could be a 4 cylinder, 6 cylinder, 8 cylinder, 10 cylinder, or 12 cylinder (the last two engines are mainly used in exotic cars). There are also rotary engines, electric engines, natural gas engines and hybrid (electric/gas) engines. Each of these has subcategories as in the most common piston engines listed above.
They are both internal combustion engines
No, they are both internal combustion engines.
Not all 4 cylinder engines are interference. When the timing belt breaks in an interference engine the valves can cause serious damage.
