The 18K4G engine is an all-aluminum turbocharged power unit with a displacement of 1.8T, designated asAVACHI.
It is widely used in various models such as the Roewe 550, Roewe 750, MG6, Huatai Saint Fe, and Dongfeng Jingyi.
Main features:
Technical Features: The 18K4G engine uses an all-aluminum block and cylinder head, effectively reducing the of the engine
and improving heat dissipation. It is also equipped with dual overhead camshafts and a four-valve structure, which allows
for more complete combustion better power performance. Additionally, the engine employs variable valve timing technology,
which can automatically adjust the valve opening based on different driving needs and speeds, further enhancing fuel and
power performance.
Performance Parameters: The 18K4G engine has a displacement of 1.8 liters, with a maximum power of approximately 30
horsepower and a maximum torque of around 220 Nm. The engine boasts high fuel efficiency and low emissions, meeting
national environmental standards, and good reliability and durability.
Despite its excellent performance at speeds, the 18K4G engine appears sluggish at low speeds, and noise becomes
noticeable when the RPM exceeds 4000. Additionally, engine may exhibit vibration during low-speed driving, and its power
output in the mid-low speed range is not as expected, which might be related to the sluggish response the turbocharging
system. Despite these issues, the 18K4G engine is known for its robustness and stable quality, with a very low failure, wide
fuel adaptability, and excellent fuel economy.
