What are the differences between gasoline and diesel
Gasoline vs. Diesel Engines: What You Need to Know
When it comes to auto engines, you may have heard some people use the terms “gasoline” and “diesel” interchangeably. You’ve also probably seen the two types of fuel options while filling up at a gas station. But do you truly understand the major differences between gasoline and diesel engines? The diesel repair experts at C&M Automotive & Transmission in Simi Valley, California are here to give you the answers.
Both diesel and gasoline engines use internal combustion and a sequence of rapid explosions to convert the fuel into energy used to power the vehicle. Internal combustion simply means that fuel combustion, or the burning of fuel, takes place on the inside of the engine. The significant difference is how the explosions happen.
In a gasoline engine, fuel is mixed with air compressed by the pistons. Spark plugs then ignite the mixture to power the vehicle. Diesel engines don’t have spark plugs. Instead, they use extreme compression to generate hot air. The fuel ignites when it hits the hot air.
Diesel and gas engines inject fuel differently. In a diesel engine, the fuel is directly injected into the cylinder. In a gasoline engine, fuel can be injected by a port injection system or a carburetor. The carb combines air with the fuel before sending it into the cylinder for compression.
Diesel engines are far more efficient than gasoline ones and can deliver greater fuel economy. This is due to diesel engines having higher compression ratios. Since they don’t mix fuel with the air during the intake stroke, diesel engines can compress the air more than gas engines can.
For folks looking for a powerful vehicle, they often consider the horsepower and torque. Horsepower is a power measurement, and torque is the engine’s rotational force, or how much work the engine exerts to get the vehicle going. Diesel engines have more torque but less horsepower than gasoline engines. This is why you’ll see diesel powered trucks get off to a slow start compared to gas powered muscle cars that take off right away. The big trucks need the added torque to move heavy loads while the sports car needs plenty of ponies to keep them fast.
Gasoline vs. Diesel Engines Advantages
Gas engines are cheaper to maintain, have lower fuel costs, and are more widely available than diesel engines. On the other hand, diesel engines have superior towing power, more efficiency, and higher resale values.
