Forklift Engines
Forklifts are classified as vehicles with small engines. Forklift engines all follow the principles of internal combustion, while the many makes and models of lift truck will have a different design and layout. Forklifts are made more toward generating high torque rather than for speed. They normally are geared to low speeds. The engine runs the drive wheels of the forklift. The engine is also required to raise and lower the forks via a series of chain pulleys. The majority of modern forklift engines are powered by propane since they will be utilized indoors, where diesel and gasoline engines will be inappropriate due to the exhaust they create.
Normally, the lift truck is a four-cylinder engine-block. The engines of the forklift are similar to car engines because they hold pistons connecting to a camshaft. The head of each cylinder consists of an exhaust hatch, a spark plug and an exhaust hatch, each of them one-way and spring-loaded.
Engine Function
Once the driver starts up the engine of the forklift, propane passes through the opened throttle-plate in a fine spray and mixes together with air coming from the mass air intake before moving into the head intake hatches of the cylinder. Every one of the four pistons is staggered to rise in a precise sequence, that compresses the mixture of propane and air as every piston rises to the top of the head. With extremely precise timing, the alternator and battery of the engine create an electrical current which passes through the spark plug. The fuel ignites resulting in an explosion which 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 the exhaust hatch to draw out exhaust when more fuel passes into the cylinder. Propane burns a lot cleaner than gasoline and diesel and the exhaust is not as harmful.
