What brand is the 4RB2 engine?

[LeKatherine]

4RB2 engine is a brand of Toyota, which is a technical improvement based on Toyota's 2RZF-E prototype, and its performance is better than the prototype. Engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. Detailed introduction of 4RB2 engine: Currently, Toyota in Japan produces 4,500 units per month, with a cumulative production of 800,000 units. It is mainly suitable for models such as Toyota Hiace, Hilux, Granvia MPV, light trucks, and station wagons. In China, the main matching models are: Jinbei Hiace; Jinbei Granvia; Changfeng Leopard SUV; BAW Land King, FAW Dongfeng pickup, Nissan pickup, etc. Engine model 4RB2, intake form naturally aspirated, cylinder arrangement inline, displacement 2.438L, maximum output power 102kW, rated speed 4600-5000rpm, maximum horsepower 139 horsepower, maximum torque 217N.m, maximum torque speed 2600-3200rpm, full load minimum fuel consumption rate 260g/kW.h, engine type inline four-cylinder, four-stroke, water-cooled, naturally aspirated, DOHC (double overhead camshaft), 16V (16 valves). Daily maintenance methods for the engine: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected according to the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to the mechanical load, and the selection standard should not be lower than the requirements specified by the manufacturer. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance will deteriorate, causing various problems for the engine. To avoid failures, the oil should be changed regularly according to the usage conditions, and the oil volume should be moderate. When the oil passes through the fine holes of the filter, the solid particles and sticky substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, the filter element will burst or the safety valve will open, allowing the oil to pass through the bypass valve, still bringing dirt back to the lubrication part, accelerating engine wear and internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, mixing with metal powder generated by part wear to form sludge. When the amount is small, it is suspended in the oil; when the amount is large, it precipitates from the oil, blocking the filter and oil holes, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale can not only ensure the normal operation of the engine but also extend the overall life of the radiator and the engine.
