Forklift Engines
Forklifts are classified as vehicles with small engines, the same category in which lawnmowers are categorized. The engines of the forklifts all follow the principles of internal combustion. Various lift truck brand names and models would have varying engine design and layout. Forklifts are made more toward producing 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 needed to lower and lift the forks through a series of chain pulleys. Most forklift engines which are modern are fueled by propane since they would be utilized indoors, where diesel and gasoline engines will be inappropriate because of the exhaust they produce.
A four-cylinder engine-block is usually found in a lift truck. A lot similar to the engine in small automobiles, forklift engines have cylinders that contain pistons connecting to a camshaft. Each and every cylinder head has an exhaust hatch, a spark plug and an exhaust hatch, each of them spring-loaded and one-way.
Engine Function
When the driver starts up the forklift engine, propane passes through the opened throttle-plate in a fine spray and mixes together with air which comes from the mass air intake prior to moving into the cylinder head intake hatches. Each one of the four pistons is staggered to rise in a precise sequence, compressing the mixture of propane and air as every piston rises to the top of the head. With really precise timing, the battery and alternator of the engine generate an electrical current that passes through the spark plug. The fuel ignites resulting in an explosion that drives the piston back down to the bottom of the cylinder, resulting in a continuous turning of the camshaft. An air pressure imbalance in the cylinder causes the exhaust to be drawn out through the exhaust hatch as more fuel passes into the cylinder. Propane burns cleaner compared to gasoline and diesel and the exhaust is not as harmful.
