What are the Toyota engine models?

Depending on the different models under Toyota, the engines also vary. The engine model is 9NR/8NR, with a maximum horsepower of 116 hp, maximum power of 85 KW, maximum power speed of 5200-5600 rpm, and maximum torque of 185 Nm. The engine model is M20A/M20E, with a maximum horsepower of 178 hp, maximum power of 131 KW, maximum power speed of 6600 rpm, and maximum torque of 210 Nm. The engine model is A25A/A25G, with a maximum horsepower of 209 hp, maximum power speed of 6600 rpm, maximum power of 154 KW, and maximum torque of 250 Nm. Toyota car engines are produced according to the vehicle's origin: domestic model engines are produced in China; imported model engines are produced in Japan, Southeast Asia, or the United States. For daily maintenance of Toyota engines, the following methods can be used: use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the manufacturer's 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 according to 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 blocked and oil cannot pass through the filter element, it will burst the filter element or open the safety valve, bypassing and bringing dirt back to the lubrication area, accelerating engine wear and increasing 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 cylinder wall, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking the filter and oil holes, making engine lubrication difficult and causing wear; regularly use a 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.
As someone who has worked with Toyota vehicles for a long time, I've seen many common engine models. Small cars often use the 1NZ series, which was popular in older Corollas—fuel-efficient and durable, though the spark plugs occasionally need replacing. V6 engines like the 1GR-FE are found in the Highlander or Land Cruiser, delivering strong power but with higher maintenance costs, especially prone to carbon buildup in hot climates. Modern hybrids, such as the Prius's 1.8L engine paired with an electric motor, are quiet and fuel-efficient, though battery maintenance is crucial. Then there's the entry-level 4A series, often found in older cars and prone to oil burning, requiring regular fluid checks. Knowing these models helps owners save on repairs—I recommend consulting the manual or a repair shop for guidance.
