Ever wondered why diesel engines operate differently from their gasoline counterparts, especially when it comes to ignition? What exactly sets diesel engines apart, and why don't they need spark plugs? The Principle of Compression Ignition Unlike gasoline engines, which use spark plugs to ignite a precisely mixed air-fuel mixture, diesel engines rely on compression ignition. This means that the air is compressed to such a high pressure and temperature within the cylinder that it spontaneously ignites the injected fuel without the need for external ignition sources. This highly efficient process allows diesel engines to operate at higher compression ratios, resulting in better fuel economy and torque. Eliminating the Spark Plug One of the main reasons why diesel engines don't use spark plugs is their reliance on compression ignition. By eliminating the need for spark plugs, diesel engines simplify their design and reduce the number of compon ... read more
