Diesel Fuel versus Gasoline Gasoline and diesel are both fuels that start off as mined crude oils that are refined into various kinds of fuels. How to Tell the Difference Between a Gas and Diesel Car In the past you could tell the difference between a gas or diesel powered car simply by the sound it produced. Here are three ways to tell if a car uses gas or diesel: Look under the hood. Look at the engine and identify whether there are spark plugs, a throttle body, or a mass air flow sensor.
Diesel engines do not have spark plugs and some older models may operate without the throttle body or the mass air flow sensor. Check the Fuel Cap. You can also check the size of the fuel filler neck. Vehicle Name. Trucks typical have diesel displayed in multiple areas on the vehicle. Email me this coupon. Print this coupon.

First of all, unlike a car powered by electricity or cold fusion, a diesel-powered car is not much different from a gas-powered one. They both contain internal combustion engines that convert liquid fuel into mechanical energy.
The main difference between these engines is how their internal combustion processes work. To briefly explain internal combustion: Explosions generated in the piston chambers push the pistons up, the pistons turn the crankshaft, and the crankshaft spins the wheels. In a gasoline engine, fuel is mixed with air inside a piston chamber, compressed by a piston and ignited by a spark plug. He believed there had to be a more efficient solution, and he set out to discover it.
In , he invented and patented what was at that point called the combustion power engine. Today, we know it as the diesel engine. In the basic sense, gas and diesel engines have similar operations. Both engines use internal combustion and a series of rapid explosions within the engine to turn fuel into mechanical energy and propel a vehicle forward. The difference is how these explosions occur.
In a gasoline engine, the fuel mixes with air compressed by pistons. The spark plugs ignite this mixture to move the vehicle. On the other hand, in a diesel engine, the air is first compressed. This makes the air hot. The fuel then ignites when it hits the hot air. Gasoline and diesel engines inject fuel in different ways. In a gasoline engine, fuel injection can occur two ways: a port injection system or a carburetor.
The port injection system injects air into the fuel right before the intake stroke. In contrast, a carburetor mixes the fuel and air together before sending it into the cylinder to compress. In a diesel engine, the fuel is injected directly into the cylinder. Since this process is a crucial part of how diesel engines work, the diesel injectors can become a complicated part of the process. In order to deliver the fine mist of fuel necessary for the process to work, the injectors must be able to withstand high temperatures and a large amount of pressure.
To this day, engineers are working to make this system more efficient. Examples of engine advancements include engine control modules and glow plugs.
