Volvo 400 Series Engines

The Volvo 400 Series used a wide range of different engine versions, largely based on Renault collaboration. Engines are best identified by their type code, which indicates the fuel system and equipment (e.g., catalytic converter or turbo).

The 1.7-liter (1721 cm³) is the series' most common engine, manufactured in several different versions: Carburetor models: B18K, B18KP: Carburetor engine without catalytic converter. B18K(D), B18KP(D): Carburetor engine with catalytic converter. Injection models (Fenix): B18E, B18ES: Multi-point injection (Fenix 1 or 3.2) without catalytic converter. B18E(D): Multi-point injection (Fenix 1 or 3.2) with catalytic converter. B18EP: Multi-point injection (Fenix 3B) without catalytic converter. B18FP: Multi-point injection (Fenix 3B) with catalytic converter. Injection models (Bosch): B18F: Bosch LH-Jetronic multi-point injection with catalytic converter. Turbo models: B18FT(M): Turbocharged multi-point injection (Bosch LH-Jetronic) with or without catalytic converter.

In addition to the 1.7-liter, the lineup included the following engines: 1.6-liter engine (B16): Displacement 1596 cm³. 1.8-liter engine (B18U): Displacement 1794 cm³. Equipped with Bosch/Siemens single-point injection and catalytic converter. 2.0-liter engine (B20F): Displacement 1998 cm³. Equipped with Fenix 3B multi-point injection and catalytic converter.

Engine size / Exact displacement 1.6 / 1596 cm³ 1.7 / 1721 cm³ 1.8 / 1794 cm³ 2.0 / 1998 cm³

Certain models, such as the B18ES, are equipped with exhaust gas recirculation (EGR) and supplemental air system (Pulsair), which helped reduce emissions before catalytic converters became widespread.
