On the intake stroke, the piston starts at the top of the cylinder. The intake valve opens as the piston moves down, allowing the engine to draw in a blend of air and gasoline. During the compression stroke, the piston moves back up and compresses the gas and air mixture. At the top of the compression stroke, the As the gas burns and expands, it pushes the piston down in the combustion stroke, completing the cycle. After that the piston moves back to the top of the cylinder, pushing the burned gases out of the exhaust valve. Diesel engines follow the same four-stroke cycle as a gas motor, with one major difference. In contrast to a Differences Between Gas and Diesel Engines Spark Plugs: A gas engine uses a spark plug to Some diesel engines do have something called glow plugs, however. In cold temperatures, diesel engines can have trouble starting because the compressed air isn't hot enough to ignite the fuel in a cold cylinder. Glow p...

But that third step, when the fuel is ignited, is when things start to differ. A gasoline engine uses something called a Diesel engines don’t have spark plugs. Instead, the air and fuel are much more compressed. And that rapid compression generates heat, which lights the gasoline rather than an external spark. That’s the simple, SparkNotes explanation. But if gasoline engines and diesel engines use the same four-stroke process, why can’t they use the same fuels. What’s the difference between gasoline and diesel? A man pumping gas | Indranil Aditya, NurPhoto, Getty Images There are two main differences between With that said, don’t ever use diesel fuel in a gas engine or gasoline in a diesel engine. Unless you want to destroy the engine, in which case go ahead. Putting diesel in a gasoline car would clog up the fuel pumps and injectors, which weren’t designed to handle the heavy mixture. Now, diesel engines are incredibly durable, capable of running on different fuels such as This is partly because all the aforementioned fuels, and diesel itself, are closer to oil. They have lubricating qualities that keep the engine operating silky smooth as the diesel flows through it. In other words, if diesel fuel didn’t have that lubricating quality, it’d gunk up the engine. Gas is just gas, it wasn’t meant to lubricate anything, which would damage the parts and total the engine. So don’t mix up the two, that’d be a nail in the coffin for your car. But when you put the right kind of fu...

In theory, diesel engines and Both diesel engines and gasoline engines convert fuel into energy through a series of small explosions — or combustions. The major difference between diesel and gasoline is the way these explosions happen. 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. • Intake stroke: The intake valve opens up, letting in air and moving the piston down. • Compression stroke: The piston moves back up and compresses the air. • Combustion stroke: As the piston reaches the top, fuel is injected at just the right moment and ignited, forcing the piston back down. • Exhaust stroke: The piston moves back to the top, pushing out the exhaust created from the combustion out of the exhaust valve. Remember that the diesel engine has no spark plug that intakes air and compresses it; instead it injects the fuel directly into the combustion chamber (direct injection). It is the heat of the compressed air that lights the fuel in a diesel engine. In the next section, we'll examine the diesel injection process. Compression When working on his calculations, Rudolf Diesel theorized that higher compression leads to higher efficiency and more power. This happens because when the piston squeezes air with the cylinder, the air becomes concentrated. Diesel fuel has a high energ...
