What brand is the 4RB2 engine?

[DelHope]

4RB2 gasoline engine is a domestic engine produced by Mianyang Xinchen Power Machinery Co., Ltd. It is an optimized domestic model based on Toyota's 2RZ-FE engine technology, featuring a lightweight and high-rigidity cylinder block, with the cylinder head made of aluminum alloy casting. Maximum output power is 102kW, rated speed 4600-5000rpm, maximum horsepower 139hp, maximum torque 217N.m, and maximum torque speed 2600-3200rpm. For daily maintenance of the 4RB2 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, choose SD--SF grade gasoline engine oil based on the additional devices of the intake and exhaust system and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid faults, change the oil regularly based on usage conditions and keep the oil volume moderate. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, it will either burst the filter element or open the safety valve, allowing oil to pass through the bypass valve and carry contaminants back to the lubrication area, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder wall, mixing with metal powder from part wear to form sludge. Small amounts remain suspended in the oil, while large amounts precipitate, clogging filters and oil holes, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.
