Forklift Engines

Forklifts are classified as vehicles with small engines, the same class wherein lawnmowers are classed. Forklift engines all follow the principles of internal combustion. Different lift truck brand names and models will have varying engine design and layout. Forklifts are designed more toward generating 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 raise and lower the forks via a series of chain pulleys. The majority of forklift engines which are modern are powered by propane since they would be utilized for indoor applications, where gasoline and diesel engines would be inappropriate because of the exhaust they produce.



Normally, the lift truck is a four-cylinder engine-block. Forklift engines are like car engines as they hold pistons connecting to a camshaft. Each and every cylinder head consists of an intake hatch, an exhaust hatch and a spark plug, each of them spring-loaded and one-way.



Engine Function

Propane passes through the opened throttle-plate in a fine spray, when the operator starts up the engine of the forklift. This fine spray mixes with air coming from the mass air intake before moving into the head intake hatches of the cylinder. Each one of the four pistons is staggered to rise in a precise sequence, compressing the propane and air mixture as every piston rises to the top of the head. With timing which is really precise, the alternator and battery of the engine produce an electrical current which passes through the spark plug. The fuel ignites leading to 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 the exhaust hatch to draw out exhaust when more fuel passes into the cylinder. Propane burns cleaner compared to gasoline and diesel and the exhaust is not as harmful.
