Lift truck Engines
Forklifts are classified as vehicles with small engines. The engines of the forklift all follow the principles of internal combustion, though the numerous makes and models of forklift would have a different layout and design. Forklifts are made more toward producing high torque than for speed. They normally are geared to low speeds. The engine powers the drive wheels of the forklift. The engine is also required to lift and lower the forks through a series of chain pulleys. Nearly all forklift engines which are modern are fueled by propane because they will be utilized for indoor applications, where diesel and gasoline engines would be inappropriate due to the exhaust they produce.
Typically, the forklift is a four-cylinder engine-block. Forklift engines are like automobile engines because they hold pistons connecting to a camshaft. The head of each and every cylinder has a spark plug, an intake hatch and an exhaust hatch, each of them spring-loaded and one-way.
Engine Function
Propane passes through the opened throttle-plate in a fine spray, once the operator starts up the forklift engine. This fine spray mixes with air coming from the mass air intake prior to moving into the cylinder's head intake hatches. Every one of the four pistons is staggered to rise in an exact sequence, that compresses the air and propane mixture as every piston rises to the top of the head. With timing that is really precise, the alternator and battery of the engine generate 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, causing a continuous turning of the camshaft. An air pressure imbalance in the cylinder causes the the exhaust hatch to draw out exhaust as more fuel passes into the cylinder. Propane burns a lot cleaner than gasoline and diesel and the exhaust is not as harmful.
