The compression function compresses the mixture. The power function involves igniting the mixture and harnessing the power of that reaction. The exhaust function expels the burned gases from the engine. In a four-stroke engine, the combustion process is made up of the 1) intake, 2) compression, 3) power and 4) exhaust strokes. Before we explore the rotary engine, let's review the basic workings of a normal piston-combustion engine. The piston is connected to a crankshaft via a connecting rod, and as it moves up and down it makes the crankshaft rotate. Opposite the crankshaft is a combustion chamber with valves that let in fuel and air, and let out exhaust gasses. oK8Oo. Diesel engines have a much slower operating speed than gasoline, and that goes double for the massive ones used in locomotives. The large displacement diesel engine tops out at about 2,100 rpm, or lower. With a speed range like this, a locomotive would need 20 or 30 gears to make it up to 110 mph. Before we explore the rotary engine, let's review the basic workings of a normal piston-combustion engine. The piston is connected to a crankshaft via a connecting rod, and as it moves up and down it makes the crankshaft rotate. Opposite the crankshaft is a combustion chamber with valves that let in fuel and air, and let out exhaust gasses. Combustion. Rotary engines are equipped with two spark plugs. Since the combustion chamber is pretty long, two spark plugs are required to spread the flame. As the spark plug ignites the air/fuel blend, the building pressure pushes the rotor to move further. As the rotor marches on, the volume of the chamber grows. Four Strokes, Two Methods. The steps are outwardly the same: intake, compression, combustion and exhaust. The difference is in the details. On the intake, gas engines pull in air and fuel, while diesel takes only air. During compression, the piston moves up, compressing the chamber contents (air and fuel in gas, air only in diesel). Most of the tractors are fitted with Diesel Engines with Direct Injection systems. These engines are categorised based on horsepower generated from them. Nowadays, engines from 12 Hp to 120 Hp are available. Apart from this, most of the engine works on the four-stroke cycle. And the crankshaft of a traditional engine rotates in response to
