Preventing Hunting and noisy engine
Hunting can be prevented by using higher-octane gasoline, keep the engine working at normal temperature with the cooling system to maximize performance and reduce the compression ratio. Of the three, the easiest is to use high-octane gasoline and keep the cooling system to work properly.
To reduce the compression is not easy (usually replace gasket or cylinder head gasket with a thicker). In addition, the effects appear less favorable, the efficiency of the engine work down. Except for the engine equipped with a turbocharger or supercharger.
Using high-octane machine, resulting in increased operational costs. However, durability and efficiency of the machine work better. Performance is also okay! Fuel consumption, liters / km more efficient.
However, the use of this type of fuel the engine with the engine and the valves have been met coal deposit or crust, will not be able to resolve the problem. Crust on the machine must be cleaned. Higher-octane gasoline is very helpful when used since the machine was new.
Keeping the cooling system working normally very important. Engine temperature should not be too high. In this case, not only media, such as liquid cooling (coolant), as well as components such as thermostats, water pumps, pipes, hoses and radiator cap.
Even the radiator surface to facilitate clean and thus more heat release. Radiator can get dirty from mud or splash of a variety of impurities. However, to know the machine work, just monitored through temperature indicator and cooling liquid in the reservoir.
Cooling the engine can also be assisted by the use of better quality oil. Duty oil or lubricant on the engine not only lubricate all surfaces rub together, also mendinginkanya. Removing the heat generated motor oil. A good oil, should be able to lead and releasing heat quickly.
How to Drive
Do not be too pushy machine working with a heavy load. For example, the low round but high gear. Immediately move the lower teeth and do keposisi gradual acceleration. Once-accelerate machine must also running at high or maximum rotation is constant so the dirt can get out of the engine and exhaust system.
Hunting also occurs when the engine is turned off and called dieseling. Symptoms, when the ignition is OFF, the engine was still alive a few moments. Such conditions are potentially occur in the machine that still rely on the carburetor.
Dieseling occurred because the engine is very hot (temperature above normal), and many piles of charcoal in the engine. Fuel is still entered into the machine, through the combustion process several times. Combustion triggered by burning charcoal or high engine temperatures. In addition to noise, fuel consumption is also a very wasteful.
