Is the 4J12 an imported engine?

4J12 engine is a domestically produced engine, manufactured in Hunan, and is one of the engines under Mitsubishi. The Mitsubishi Outlander 2.4L version is equipped with the 4J12 engine, with a maximum power of 141kw and a maximum torque of 235 Nm. Daily maintenance methods for the 4J12 engine include: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices of the intake and exhaust systems 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 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 failures, change the oil regularly according to usage conditions and keep the oil level moderate; When oil passes through the fine pores 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 either burst the filter element or open the safety valve, bypassing through the bypass valve and bringing contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution; 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 walls, mixing with metal powder from part wear to form sludge. When the amount is small, it suspends in the oil; when large, it precipitates from the oil, blocking 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 the normal operation of the engine but also extends the overall lifespan of the radiator and engine.
As a car enthusiast, I often study engines. The 4J12 is indeed an imported engine, primarily used in SUVs like the Mitsubishi Pajero. I've seen the actual unit at an auto show and was impressed by its fine craftsmanship, as it's directly shipped from Japan. The V6 design of this engine is quite classic, delivering sufficient horsepower while being fuel-efficient. However, extra care is needed with spare parts during maintenance, as imported components sometimes require longer waiting periods. Overall, being imported signifies higher quality, but don't overlook the importance of regular oil system checks to avoid unexpected breakdowns.
I've worked in the auto repair shop for over 20 years and have hands-on experience repairing many Mitsubishi engines. The 4J12 is basically an imported model, and when repairing it, parts often need to be ordered, which is quite troublesome. Once, I worked on an old Pajero, and the owner said it had an imported engine with very stable power output. I recommend regular oil changes, as imported engines are more sensitive to oil quality, helping to avoid clogged fuel injectors and extend engine life. Always pay attention to changes in engine sound while driving to detect problems early.
