Mitsubishi 6G7 Engine Series: A Comprehensive Overview
Introduction
The Mitsubishi 6G7 engine series is a family of V6 engines produced by Mitsubishi Motors. These engines are known for their power, reliability, and adaptability, making them a popular choice for a wide range of vehicles, including sedans, coupes, SUVs, and trucks.
Engine Design and Architecture
All 6G7 engines feature a 60-degree V6 configuration with a single overhead camshaft (SOHC) or double overhead camshafts (DOHC) per cylinder bank. The SOHC engines use two valves per cylinder, while the DOHC engines use four valves per cylinder. The engines have a cast-iron block and aluminum cylinder heads, with a bore and stroke of 91.1 mm × 76.0 mm, resulting in a displacement of 3.0 liters.
Power and Performance
The 6G7 engines offer a wide range of power and performance characteristics depending on the specific variant. The base SOHC engine produces around 145 horsepower and 180 lb-ft of torque, while the more powerful DOHC engines can generate over 200 horsepower and 230 lb-ft of torque. The engines feature a multi-point fuel injection system and electronic ignition for optimal combustion and efficiency.
Intake and Exhaust Systems
The 6G7 engines utilize a variable intake manifold to optimize air flow and boost low-end torque. The variable intake system adjusts the length of the intake runners to match the engine's operating conditions, improving both power and fuel economy.
The exhaust system features a catalytic converter and oxygen sensor to reduce emissions while maintaining performance. Some variants also incorporate an exhaust gas recirculation (EGR) system to further reduce nitrogen oxide (NOx) emissions.
Cooling and Lubrication Systems
The 6G7 engines are equipped with a liquid cooling system that utilizes a water pump, radiator, and thermostat to maintain optimal engine temperature. The lubrication system employs a wet-sump design with an oil pump to circulate oil throughout the engine components.
Durability and Reliability
The Mitsubishi 6G7 engines are renowned for their durability and reliability. They feature robust construction, high-quality materials, and precision engineering, providing exceptional longevity and performance even under demanding operating conditions.
Applications and Legacy
The 6G7 engine series has been used in a wide range of Mitsubishi vehicles, including the Galant, Eclipse, Montero, and Pajero. The engines have also been exported to other markets and used in vehicles from other manufacturers, such as the Hyundai Sonata and Kia Sedona.
The 6G7 engines have earned a reputation for their versatility, power, and reliability, making them a popular choice for both OEMs and aftermarket enthusiasts. They continue to be sought after for performance upgrades and engine swaps due to their robust design and impressive capabilities.
