About Honda engine:

Honda engine is one of the top engine manufactures globally. Honda earned an excellent reputation due to the quality and high-performance engine they made. Engine manufactured by the Honda is durable with exceptional fuel efficiency.

Additionally, the engines are easy to use, maintain, and produce high power, which in return makes the superior in performance. Honda engines for tamping rammer, come with varieties of features, and these engines are not one similar to each other. In this regard, the engines are designed to cater to the different needs of their customers.

Honda engines are available to almost every field. For example, there is those used in the agricultural area- like mowers is a perfect example; others are used to pump water, industrial machine run by Honda manufactured engines.

About OHV:

Their engines are environmental-friendly; no pollution because the motors are equipped with the overhead valve (OHV), which ensures smooth fuel uptake, enhancing complete and quick combustion. OHV also plays a very critical role in increasing the life span of the engine.

It is fuel efficiency, the overhead Valves (OHV); these valves are the exhaust and the intake valves, which are timed to enhance smooth fuel intake and quick and continuous exhaust emission. This is made possible by the maximum and timely overlapping of the two valves, which increases the maximum compression ratio, hence produces much heat require to combustion an air-fuel mixture

Here, we’re not going to talk about post rammer nor palenrammer in this artile, we just focus on tamping rammers with Honda engines

Honda engine usage:

Honda engine is a re-known engine applied in massive works, and it is used in constriction of houses and roads. Most of the roads constructing companies rely on this engine for compaction purposes. Honda Rammer is one use in landscaping, trenches, and sewage compaction application. This is made possible by a vibrating tampered; other applications include pumping, spraying, mowing, making commercial lawn, etc.

These kinds of engines also be used to pump water for irrigation, mowing, spraying, used for commercial lawn, and used to run machines in manufacturing industries and construction industries.

Environmental friendly. GX100 is designed and modified in such a way that the air-fuel mixture is wholly ignited. This is enhanced by timely overlapping valves and maximum compression offer in the combustion chamber. In this regard, the gas emitted to the environment less poisonous. Also, the GX100 engine is noise-free; as compared to the engines, GX100 is relatively quiet. This is made possible by the extensive exhaust system and rigid crankcase, which retains the sound and reduces noise.

Additionally, the GX100 is easy to use, manage, and maintain. Fuel tank, a spark plug is easily accessible. Therefore the engine is user friendly. Starting GX100 Honda is very easy as it is designed with an automated decompression system, which helps give a quick and easy start.

Importantly, GX100 Honda is reliable where it is automated with an oil alert system that detects and alarms when the oil is low for safe operation. When the oil is low below the secure operation engine, either alert or stop automatically. This very important as is reduces the maintenance cost and increases the durability of the engine.

GX120 is developed for equipment used to compact soil or granular soil- therefore referred to as Rammer, designed for massive duty operations. GX120 engine is mainly applied in commercial Rammer. The features of the GX120 are the same as that of the GX100. Although it produces a tremendous amount of power, displacement is also higher. The lubrication is by forced spray. Contrary to GX100, GX120 is small in size with a dry weight of 10.4 kg.


GX160 engine is designed the same as the GX100 Honda engine, and applications are also identical. Despite this, it is the largest of all the three engines, with a dry weight of 14.5kg and produces more power as compared to either GX100 or GX120 Honda Rammer. Oil lubrication is the same as GX100 by using a splash system.

Regular Parts

  • The valves: they are two types, exhaust valve and inlet valve.
  • The piston: bring about the compression of the air-fuel mixture
  • Combustion chamber here air-fuel is ignited.
  • Spark plug: ignite air-fuel mixture contained in the combustion chamber.
  • Fuel tank
  • Carburetor: Mixes air and the fuel before entering the combustion chamber.
  • Air cleaner: remove and prevent dust from entering the carburetor
  • Lubrication system, the function of this system is to minimize engine overheating, reduce friction between the moving gears.
