system, which reduces their plexity. However, they also create more noise, they can be difficult to start in extremely cold weather and they sometimes require more frequent routine maintenance than gasoline engines. Most passenger car diesel engines have a glow plug of some type. When a diesel engine is cold, the air pression may not raise the air to a high enough temperature to ignite the fuel. The glow plug is an electric heater that glows redhot and helps to ignite the fuel when the engine is cold so that the engine can start. The amount of power which an engine can produce is limited by how much fuel it can burn, and the amount of fuel it can burn is limited by the amount of oxygen in the cylinder. The amount of oxygen in the cylinder is limited by the amount of air in the cylinder. So, if more power is wanted then more air is needed, how do we achieve this? Well a large engine has more air, so it can produce more power, or we can press the air before it gets to the is what a supercharger does。s high pression ratios and the fuel injection systems. They are even nosier when they are cold. Diesel engines require more frequent routine maintenance than gasoline engines. On the plus side however, normal gasoline engine maintenance such as replacing the spark plugs, rotor and replacing ignition wires are not necessary on a diesel engine.

Is a diesel engine right for you? That is something you have to decide based on your needs and driving habits. A diesel powered vehicle will not handle or be as powerful as a gasoline powered vehicle. Diesel fuel is not as readily available as gasoline. I had more than a few times where I was sweating out finding a gas station with diesel. This, however, is starting to change with the increasing number of diesel powered vehicles now on the road. I know I love my diesel and once I adjusted to it, I can39。ll get far below the fuel economy tha
