Forklift Engines
Forklifts are classed as vehicles with small engines. Forklift engines all follow the principles of internal combustion, though the many makes and models of forklift will have a different layout and design. Forklifts are designed more toward producing high torque than for speed. They usually are geared to low speeds. The engine runs the forklift's drive wheels. The engine is also required to raise and lower the forks through a series of chain pulleys. Nearly all forklift engines which are modern are fueled by propane since they would be utilized indoors, where diesel and gasoline engines would be inappropriate due to the exhaust they create.
A four-cylinder engine-block is usually found in a forklift. Much similar to the engine in small automobiles, the engines of the forklift have cylinders which contain pistons connecting to a camshaft. The head of every cylinder consists of an intake hatch, an exhaust hatch and a spark plug, each of them spring-loaded and one-way.
Engine Function
Once the driver starts up the forklift engine, propane passes through the opened throttle-plate in a fine spray and mixes with air which comes from the mass air intake before moving into the cylinder head intake hatches. Each and every one of the four pistons is staggered to rise in a precise sequence, which compresses the air and propane mixture as every piston rises to the top of the head. With really exact timing, the battery and alternator of the engine create an electrical current that passes through the spark plug. The fuel ignites causing an explosion that drives the piston back down to the bottom of the cylinder, leading to a continuous turning of the camshaft. In the cylinder, an air pressure imbalance causes the exhaust to be drawn out through the exhaust hatch as more fuel passes into the cylinder. Propane burns cleaner than gasoline and diesel and the exhaust is not as harmful.
