Subaru is a Japanese company that specializes in the manufacturing of engines and vehicles. The company has been around for over a century, and its engines are well-known for their durability and reliability. One of the engines that Subaru produces is the 126cc 5hp engine, which is widely used in various applications. This article will provide an in-depth look at the 126cc 5hp Subaru engine diagram, its features, working, and maintenance.
Features of 126cc 5hp Subaru Engine
The 126cc 5hp Subaru engine is a four-stroke, air-cooled gasoline engine. It has a single-cylinder and an overhead camshaft (OHC) design. The engine has a displacement of 126cc, a bore of 54mm, and a stroke of 40mm. The carburetor used in the engine is a diaphragm type, and it has a fuel capacity of 2.0 liters.
The engine produces a maximum power output of 5 horsepower (HP) at 3600 revolutions per minute (RPM). The maximum torque generated by the engine is 7.54 Newton-meters (Nm) at 2500 RPM. The engine has a recoil starter mechanism, which makes it easy to start the engine.
The engine has a dry weight of 15.1 kilograms, making it easy to transport and install in different applications. The engine is also designed to be fuel-efficient, with a fuel consumption rate of 230 grams per horsepower-hour (g/HP-hr).
Working of 126cc 5hp Subaru Engine
The 126cc 5hp Subaru engine works on the four-stroke cycle principle, which consists of four strokes: intake, compression, power, and exhaust. The intake stroke involves the intake valve opening, and the fuel-air mixture is drawn into the cylinder. The compression stroke involves the compression of the fuel-air mixture, which is then ignited by the spark plug during the power stroke. The exhaust stroke involves the exhaust valve opening, and the burnt gases are expelled from the cylinder.
The engine’s OHC design ensures that the intake and exhaust valves open and close at the right time, ensuring optimal engine performance. The carburetor ensures that the correct amount of fuel is delivered to the engine, depending on the engine load and speed.
