Although at first glance it seems that the two types of engines are completely equal and have the same work items there are differences, these differences could cause considerable damage if sometime under carelessness or confusion fill the tank with the wrong fuel. There are many differences between these two types of motors however outstanding is how one start the combustion process, the petrol engines are recognised on the principle of a spark that appears inside the cylinder must be through plug, while the diesel engines are compression ignition term because the trigger that starts the combustion process is only the high temperature of the air in the compression phase which is sufficient to ignite the fuel in diesel the time this comes into
The diesel engine is a compression and bases its operation in pressurizing the gas (air) contained in the cylinder volume, reaching a high pressure and temperature above 500 ° C, which means that when this fuel is sprayed hot air pressure, generates a combustion drives the piston downward force (De Caro & Berge, 2001, 565-574). Its principle is rooted in the gas compression engines mid and late nineteenth century, they used few volatile fuels, such as kerosene or oil lamps.
How does it work?
The diesel engine works through igniting the air and gas mixture without producing spark. The temperature that initiates the combustion releases from the increased pressure which take place in the second motor, i.e. the compression time. Diesel fuel is then injected on top of compression chamber with high pressure; it is mixed and atomised with air at a very high pressure and temperature. This resulted as burning the mixture quickly. The ignition causes the gas to expand in the chamber, leading to drive the piston down (Ajav & Bhattacharya, 1999, 357-365). Thus, the rods connected to each other transmits this motion to crankshaft, it rotates and transform the linear movement of the piston to rotational
