Knowing what to check will give you a good indication of an engine’s overall condition An engine inspection may seem a huge task for individuals like me who are not trained in engines/machineries, however after speaking to some thought leaders in the industry, here are some insights that they share, and how they would go about conducting an engine inspection.
The mechanical design of internal combustion engines, particularly diesel engines is a challenging and interesting task. Since the combustion process in the diesel engine is never uniform and smooth, they are prone to more vibration and noise compared to petrol engines. Thus diesel engines require a rugged structural design. Out of the four strokes, it is only during the power stroke that a tremendous amount of force is exerted on the piston. So a single cylinder engine will always have high force non-uniformity.
Spare parts and product support are readily available. Kubota global presence provides you with localised support and spare parts availability to ensure your generator operates effectively. Quietness and Longevity are two main features that count when evaluating between a mediocre Genset and an exceptional one. Not many would say no to a generator that will run for years with minimal problems and low noise level, however there aren’t many manufacturers in the market that can produce such high-quality generators. Tier 1 Manufacturers such as Kubota, are just one of the brand that can achieve such high specifications.
Torque is one of the main considerations when vehicles or machinery are designed to use diesel engine. High torque is needed to move heavy loads. While Torque is defined as a measure of how much force acting on an object causes that object to move. The higher torque comes from the need for a higher compressing ratio needed for compression ignition. To achieve the higher compression ratio a longer stroke is required. The longer stroke comes from a greater crankshaft offset. This offset gives greater torque. Thus diesel engines have comparatively larger compression ratio, as a result it has a larger offset in crankshaft, resulting in higher torque. Another aspect is that diesels can make tremendous torque at very low RPM. Very simply put, more fuel equals more torque when everything else is kept the same. A diesel does not have throttle plates and draws in the maximum amount of air on every stroke. In a diesel the amount of fuel added is what controls the power. The throttle controls how much fuel is added. This means that a diesel always runs lean. At idle the engine uses hardly any fuel. This lean mixture allows for the addition of large quantities of fuel even at low RPM. A gasoline engine on the other hand always has to keep the fuel mixture at optimal stoichiometric. This need to keep the mixture correct means that to get more fuel the engine needs to rev to higher RPMs. This means that a gasoline […]
