Volvo B18 Engine

Volvo B18 Engine

This B18 was a straight-4 automobile engine produced by Volvo Cars from 1961 through 1968. The five-bearing, cam-in-block engine, had OHV overhead valves operated by pushrods. The B18 is quite different in design from its predecessor, the three-bearing B16.

These engines are reputed to be very durable. The world's highest mileage car, a 1966 Volvo P1800, has run all its more than 4,000,000 km (2,500,000 mi) on its original B18 engine.
