Lift truck Engines
Forklifts are classified as vehicles with small engines, the same category wherein lawnmowers are classed. Forklift engines all follow the principles of internal combustion. Various lift truck models and brand names would have varying engine design and layout. Forklifts are made more toward generating high torque than for speed. They normally are geared to low speeds. The engine runs the forklift's drive wheels. 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 because they will be utilized indoors, where gasoline and diesel engines will be inappropriate due to the exhaust they make.
Normally, the lift truck is a four-cylinder engine-block. Forklift engines are similar to automobile engines as they hold pistons connecting to a camshaft. Each and every cylinder head 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, when the driver starts up the forklift engine. This fine spray mixes together with air which comes from the mass air intake before moving into the cylinder's head intake hatches. Each one of the four pistons is staggered to rise in a precise sequence, compressing the air and propane mixture as each piston rises to the top of the head. With timing which is very precise, the battery and alternator of the engine produce an electrical current that passes through the spark plug. The fuel ignites leading to an explosion which 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 cleaner compared to gasoline and diesel and the exhaust is not as harmful.
