What is the 4G20D4B engine?

[SanRiley]

4G20D4B is the engine of the Jinbei Haise 2.0 Power King, which belongs to the domestic Mitsubishi engine series. It adopts a naturally aspirated intake method, with 4 cylinders arranged in an L-shape. The maximum engine speed reaches 5200 rpm, delivering a maximum horsepower of 122Ps. Within the 3600-4400 rpm range, it can achieve a maximum torque of 180N·m. Additional Information: The 4G series engines are mature products mass-produced by Mitsubishi Motors Japan, which have reached world-class levels in terms of structure, performance, and reliability. They feature compact structural designs, with smaller external dimensions and lighter weight compared to engines of the same displacement. The main components of the engine have high rigidity, and the main moving parts are designed with lightweight materials to reduce friction loss. The engines utilize high-efficiency combustion methods such as rolling combustion and optimal fuel injection.

I heard friends talking about the 4G20D4B engine, a classic powerplant introduced by Mitsubishi from the late 1980s to the 1990s, renowned for its reliability and daily usability. This engine typically features a 2.0-liter four-cylinder design with DOHC and 16-valve technology, delivering around 130 to 150 horsepower. While not particularly powerful, it runs exceptionally smoothly with low noise levels and decent fuel efficiency, making it ideal for regular family cars like older Lancer or Delica models. Maintenance is straightforward with readily available parts, which made it a favorite among drivers back then due to its durability. You can still spot it in used cars today—with proper care, it can easily clock hundreds of thousands of miles. Just remember to check the oil and cooling system regularly, replace filters periodically, and prevent carbon buildup. Though not the latest in technology, this veteran remains a solid and dependable choice.

I've driven with the 4G20D4B engine for several years. It's a classic Mitsubishi powerplant, featuring a 2.0L displacement, with DOHC twin-cam and electronic fuel injection as its highlights. Widely used in many 1990s models, it delivers smooth power output suitable for urban commuting, with modest fuel consumption averaging around 8L/100km, though throttle response lags during sudden acceleration. Maintenance is affordable – minor issues can often be fixed by replacing spark plugs or belts, and parts are readily available. Compared to modern turbocharged engines, it's more durable but less performance-oriented, ideal for drivers who prioritize reliability over excitement. Avoid overloading and adhere to regular maintenance to prevent aging issues.

The 4G20D4B is Mitsubishi's 2.0-liter gasoline engine, commonly found in older vehicles. Technically, it features a DOHC layout with a 16-valve design, delivering moderate horsepower of around 130+ HP and torque of approximately 180 N·m. Known for its high reliability and simple maintenance, it may develop issues like valve oil leaks or ignition problems over time. Owners are advised to check the engine oil and air filter annually to ensure longevity.

As an engine enthusiast, I've studied the 4G20D4B, which is a representative of Mitsubishi's classic series. It's a 2.0-liter four-cylinder configuration, equipped with DOHC and an electronic fuel injection system. The power output is around 135 horsepower, delivering quick response and smooth performance, making it ideal for high-speed cruising. Fuel consumption is well controlled, though not as efficient as today's smaller displacement engines. Commonly found in older Lancers, upgrading the ignition system can still boost performance a bit. Be careful not to let the temperature get too high, and regular coolant maintenance is key.
