Forklifts are designed to withstand damage, but that doesn't guarantee that all of their components will continue to function well indefinitely. Modern forklifts have various engine and power source options, including diesel, LPG, and electric.

Forklift diesel engines are stringently built lift trucks ideal for use in harsh outdoor environments. Because of the exhaust gases and pollutants created by burning diesel fuel, diesel forklifts are designed for outdoor operation and provide various advantages.

Diesel engines are more fuel efficient than LPG engines. Diesel engines have more torque than LPG and diesel models with comparable lift capacity. This increased torque enables diesel vehicles to perform better on hills and when towing.

Forklift engines require maintenance intervals that typically include the replacement of parts due to failure or as a precaution, depending on the site circumstances, different environmental elements, and kind of use. Keeping forklift engines in excellent working order ensures their high productivity and the fulfillment of their vital function in construction sites and warehouses.

Finally, the engine type you choose is determined by your demands, application, and financial condition, with each power source offering various benefits and disadvantages based on its features.


 Forklift Engines

An internal combustion forklift uses engines that work on the theory that converts chemical energy (fuels) into mechanical energy. This process is referred to as internal combustion engines.

Many people are familiar with internal combustion (IC) engines since they are used in automobiles.

Although it functions similarly to your car, forklifts have four different types of engines.

Forklift Engine Component

This component comprises different parts of forklift engines. They include crankshaft, thrust washer sets, connecting rod bearings, pistons, flywheel housings, piston ring sets, spark plugs, starters, alternators, valve seals, carburetors, ignition wire sets, and many others.

The various components of a forklift engine are as follows:

  • Rocker arm 

  • Injection pump

  • Spark plug

  • Connecting rod

  • Crankshaft

  • Piston rings

  • Oil pump.


Rocker Arm

The rocker's arm is responsible for conveying the movement of the camshaft to the engine's intake and exhaust valves. This process happens through direct contact of these components with the tappets and according to the shaft's movement. While one end of the rocker's arms directly touches the tappet, the other is connected to the intake and exhaust valves.

So, when the camshaft cam is actuated, the rocker's arm lowers one of its sides, allowing the valve to open and enable the mixture of air and fuel to enter the combustion chamber. Both the intake and exhaust valves move in this manner. In turn, the displacement is maintained by a spring that drives the valves back to their original position.

Because the operation happens at high speeds and requires continual contact with the rocker's arms, the springs must be strong enough to survive rapid engine revolutions.

Roacker arms, like other vehicle components, are made using materials and specifications required by global engineering standards, generally with high-quality alloy steels to offer optimal strength and a longer life span for the engine.

Injection Pump

The component that pumps fuel into the cylinders of a diesel engine is known as an injection pump. 

Historically, the injection pump was powered indirectly from the crankshaft using gears, chains, or a toothed belt (typically the timing belt) that also drives the camshaft.

Spark Plug

A spark plug is a part of forklift engines that starts the explosion, which pushes the piston down in the cylinder. The energy is translated into mechanical energy to propel the forklift. Spark plugs, as the name implies, are the spark of electricity that ignites the combustion required to start your car. 

Spark plugs discharge a bolt of electricity over a small gap, igniting the fuel and air mixtures, causing the pistons to move and your automobile to start.

Connecting Rod


A connecting rod for Forklift Engines


A connecting rod is an engine part that acts as a lever arm and transmits motion from the piston to the crankshaft. The connecting rod connects the piston to the crankshaft, transferring combustion pressure to the crankpin. It enables lubricating oil to be pumped into the thrust side of the cylinder wall to lubricate the piston travel and piston rings. Connecting rods are typically composed of cast aluminum alloy and are made to withstand dynamic loads caused by combustion and piston movement.


 Forklift Engines Crankshaft


The crankshaft transfers power to the wheels through the transmission. And eventually, that's what enables the forklift to move.

Piston Rings

The piston rings channel heat from the heated piston to the engine's cooled cylinder wall/block.

Oil Pump

The oil pump's principal function is to circulate engine oil under pressure to the bearings, pistons, and camshaft. This action lubricates these systems, enables higher-capacity fluid bearings, and aids engine cooling.

Operation of an Internal Combustion Forklift 

The engine is forced to "crank over" by an ignition battery and a gear-driven starter, thereby initiating the internal combustion process. The carburetor combines flammable liquid fuel and air before injecting it into the cylinders through the valve. The piston is connected to a rod within the cylinder connected to the crankshaft.

When the spark plug ignites the explosion by introducing a spark to the compressed fuel/air combination, it produces mechanical energy. The piston and rod in the cylinder are pushed down by the explosion. Because of how the crankshafts works, the energy of the piston and rod is converted to mechanical energy.

In the block, these cylinders are linked to the crankshaft. Other components in the block include the camshaft, which uses the RPMs to open and close the valves in a precisely timed sequence.

This mechanical energy also powers the alternator or generator (located on the engine and powered by a belt), which provides power to the lift truck's electrical components. Furthermore, the electricity generated in this manner is utilized to power the power steering and lift/tilt hydraulic pumps.



Application of Internal Combustion Forklift 

An IC forklift is employed when power requirements are higher, and combustion products are not an issue. It has more hauling capability for heavy loads on rough  roads. IC forklifts, like your automobile, are unaffected by inclement weather and may operate in rain or snow.
