Lift truck Engines
Forklifts are classed as vehicles with small engines. The engines of the forklift all follow the principles of internal combustion, while the many makes and models of lift truck would have a different design and layout. Forklifts are designed more toward producing high torque than for speed. They normally are geared to low speeds. The engine runs the drive wheels of the forklift. The engine is also needed to lower and raise the forks via a series of chain pulleys. The majority of forklift engines which are modern are fueled by propane since they will be utilized indoors, where gasoline and diesel engines will be unsuitable due to the exhaust they produce.
A four-cylinder engine-block is normally found in a lift truck. A lot like the engine in small automobiles, forklift engines have cylinders that contain pistons connecting to a camshaft. The head of every 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 operator 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 one of the four pistons is staggered to rise in an exact sequence, which compresses the mixture of air and propane as every piston rises to the top of the head. With timing that is really precise, the engine's battery and alternator generate an electrical current that passes through the spark plug. The fuel ignites resulting in an explosion which drives the piston back down to the bottom of the cylinder, resulting in a continuous turning of the camshaft. In the cylinder, an air pressure imbalance causes the the exhaust hatch to draw out exhaust as more fuel passes into the cylinder. Propane burns much cleaner compared to diesel and gasoline and the exhaust is not as harmful.
