2 reasons why most internal combustion engines are multi cylinder?

State two reasons why most vehicle engines are multi-cylinder.?

Most vehicle engines are multi-cylinder because they provide a smoother power delivery and reduce vibration compared to single-cylinder engines. Additionally, multi-cylinder engines allow for more power output without significantly increasing engine size, as they can generate more horsepower through the combined work of multiple cylinders. This enhances overall performance and efficiency in vehicles.

List two reasons why small engines are more efficient than big ones?

they have small cylinder and they also fire at every second stroke.

What is the main source of Energy for Transportation Systems?

today about dicious the petrol energy......petrol energy is the part of main source of energy for transportation systems.Petroleum: The Transport Fuel Almost all transportation modes depend on a form of the internal combustion engine, with the two most salient technologies being the diesel engine and the gas turbine, since they are the lynchpin of globalization. While ship and truck engines are adaptations of the diesel engine, jet engines are an adaptation of the gas turbine. Transportation is almost completely reliant (95%) upon petroleum products with the exception of railways using electrical power. While the use of petroleum for other economic sectors, such as industrial and electricity generation, has remained relatively stable, the growth in oil demand is mainly attributed to the growth in transportation demand. What varies is the type and the quality of petroleum derived fuel being used. While maritime transportation relies on low quality bunker fuel, air transportation requires a specialized fuel with additives. It is worth having a closer look at the chemical combustion principle of hydrocarbons. For the majority of internal combustion engines, gasoline (C8H18; four strokes Otto-cycle engines) serves as fuel, but other sources like methane (CH4; gas turbines), diesel (mostly trucks), bunker fuel (for ships) and kerosene (turbofans of jet planes) are used. In a complete and perfect combustion of gasoline the following chemical reaction is achieved:(2) C8H18 + (25) O2 = (16) CO2 + (18) H2O + energyGasoline produces around 46,000 Btu per kilogram combusted, which requires from 16 to 24 kg of air. The energy released by combustion causes a rise in temperature of the products of combustion. Several factors and conditions influence the level of combustion in an internal combustion engine to provide momentum and keep efficient operating conditions. The temperature attained depends on the rate of release and dissipation of the energy and the quantity of combustion products. Air is the most available source of oxygen, but because air also contains vast quantities of nitrogen, nitrogen becomes the major constituent of the products of combustion. The rate of combustion may be increased by finely dividing the fuel to increase its surface area and hence its rate of reaction, and by mixing it with the air to provide the necessary amount of oxygen to the fuel. If all internal combustion engines worked according to the above equation, emissions and thus local environmental impacts of transportation would be negligible (except for carbon dioxide emissions). The problem is that combustion in internal combustion engines is imperfect and incomplete for two reasons

What is meant by 'unleaded gas'?

In the 1940s or 50s, gas companies started adding lead to gasoline. This increased the octane and lubricated the internal parts of engines. Then in the 1970s lead was removed for environmental reasons.

Why can petrol not be used in power stations?

Typically petrol refers to gasoline. It can be used in power plants using internal combustion engines to turn generators. However, other plants cannot use it due to it's high volatility and added costs required to store and use it. More often than not, internal combustion engine power plants use natural gas, diesel fuel or light residual fuel oils for power due to safety and reliability concerns. Large fossil fuel plant use either natural gas, coal or heavy residual fuel oils, for cost and handling reasons.

Why is your car not putting out heat when idaling?

All internal combustion engines generate heat when they run. If your automobile is not generating heat when it is idling, there are several reasons. 1. The coolant level is too low. 2. The thermostat is not opening 3. The water pump is not moving enough coolant and it could be bad. It is normal for the temperature gauge to fluctuate 20 to 50 degrees when a motor is runnning at higher speeds than when idling

Why diesel engines not suitable for 2 wheelers?

As you know, the piston in the Diesel engine compresses the air in the cylinder so that it gets extremely hot. Fuel is then injected directly into the cylinder where it ignites and causes the power stroke. Because the Diesel engine operates at very high compression ratios it has to be very strong, and therefore heavy. The injector that squirts fuel into the cylinder has to be both strong and very precise in order to force a precise amount of fuel into the cylinder. For these reasons, Diesel engines tend to be heavier than petrol engines, and more expensive because of the very precise engineering required in manufacturing the injectors. So they are not practical for fairly inexpensive 2 wheel vehicles.

Combustion reactions have impacted people?

Some people need to answer this question for urgent reasons!

What are the common reasons for a website to receive a canonical penalty from search engines?

Websites can receive a canonical penalty from search engines for reasons such as duplicate content, improper use of canonical tags, and issues with URL structure.

What does an oil filter do?

In an automobile vehicle or any other combustion engine, an oil filter removes particles from the oil that may harm the engine. The tiny particles result from any number of reasons. If the oil gets too hot the contents in the oil can change chemically (or burn) forming particle. It can result from improper fuel burning and/or microscopic gaps in the cylinder or cylinder housing allowing "junk" in the fuel mixture or incompletely combusted fuel to mix into the oil, or from friction erosion between the cylinder and the cylinder housing.

How can you fix error p0300, p0305 and p0306 for a 3.8 liter in a 2003 chrysler?

P0305 and P0306 indicates that cylinder number 6 is experiencing misfires. A misfire occurs when an insufficient amount of fuel is burning in a cylinder. A misfire from one or more cylinders can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure

Why does your clutch stick to the floor in a 92 Honda accord?

2 reasons: 1. There is no fluid in your master cylinder due to a leaking master cylinder or slave cylinder or 2. You blew your clutch
