**Mitsubishi 4G6 Engine: A Comprehensive Overview**

The Mitsubishi 4G6 engine is a series of inline-four, four-stroke, gasoline-fueled automotive engines produced by Mitsubishi Motors. Introduced in 1980, the 4G6 engine has been widely used in various Mitsubishi vehicles, including the Lancer, Galant, and Eclipse, as well as other models from Chrysler, Dodge, and Hyundai.

The 4G6 engine family comprises various displacements, ranging from 1.6 to 2.4 liters. All engines feature a single overhead camshaft (SOHC) with two valves per cylinder and a cast-iron cylinder block with an aluminum cylinder head. The cylinder head design incorporates cross-flow cylinder heads with centrally located spark plugs and hemispherical combustion chambers, contributing to improved combustion efficiency and reduced emissions.

The 4G6 engine is renowned for its robust construction and reliability. The cast-iron cylinder block ensures durability and longevity, while the aluminum cylinder head reduces weight and improves heat dissipation. The timing belt system drives the camshaft and water pump, and the engine incorporates a balance shaft to minimize vibrations and enhance smoothness.

In terms of performance, the 4G6 engine offers a balance of power and fuel efficiency. The DOHC design optimizes valve timing and airflow, resulting in improved power output and torque across the rev range. The electronic fuel injection system ensures precise fuel delivery, contributing to reduced emissions and improved fuel consumption.

Over the years, Mitsubishi has introduced various iterations of the 4G6 engine, each featuring unique characteristics and technological advancements. Some notable variants include:

• **4G61:** The original 1.6-liter version introduced in 1980, featuring a carburetor and producing around 80 horsepower.
• **4G63:** A performance-oriented 1.8-liter engine introduced in 1984, with fuel injection, a turbocharger, and producing up to 200 horsepower.
• **4G64:** A more economical 2.0-liter version introduced in 1987, with fuel injection and producing around 130 horsepower.
• **4G69:** A 2.4-liter variant introduced in 1992, featuring fuel injection and producing around 140 horsepower.

The Mitsubishi 4G6 engine has proven its versatility over the years, powering a wide range of vehicles from compact hatchbacks to performance sedans. Its combination of reliability, durability, and performance makes it a popular choice among enthusiasts and everyday drivers alike.
