Why do diesel engines not have spark plugs? A diesel engine has no spark plugs. … A spark plug has no use with diesel fuel because there is no need to ‘light’ the diesel fuel. Instead, the glow plug only heats the combustion chamber.” In combination with the piston design, and the heated chamber from the glow plugs, the diesel fuel becomes atomized into a mist.
Why do diesel engines not need spark plugs? Diesel engines, unlike gasoline engines, do not use spark plugs to induce combustion. Instead, they rely solely on compression to raise the temperature of the air to a point where the diesel combusts spontaneously when introduced to the hot, high pressure air. … The glow plug solves this.
Did old diesels have spark plugs? Diesels have never had spark plugs – they ignite the fuel by high compression pressures, which result in very high temperatures. Ignition is initiated by injecting a fine mist of fuel into the combustion chamber when the ignition point is reached.
Why do we use spark in petrol engine? Your spark plugs are what supply the spark that ignites the air/fuel mixture, creating the explosion which makes your engine produce power. These small but simple plugs create an arc of electricity across two leads which are not touching, but close enough together that electricity can jump the gap between them.

Why does my engine rattle when i turn it on?
Since these devices are operated by engine oil pressure, when the engine is off overnight, engine oil drains out of them, and it take the first few seconds of engine operation to refill them when you first start the engine each day. For those few seconds, a metallic rattle can be heard as you have experienced.

Why are mid engine cars hard to drive?
In this case, the engine is centred, usually right behind the driver, and closer to the middle of the vehicle, rather than on top of or behind the rear wheels. … Finally, because of the evenly balanced weight, mid-engine cars are sometimes harder to control when you lose traction, say, during a spin.
How a diesel engine works vs gas?
In a gasoline engine, fuel is mixed with air, compressed by pistons and ignited by sparks from spark plugs. … In a diesel engine, however, the air is compressed first, and then the fuel is injected. Because air heats up when it’s compressed, the fuel ignites.
