The New BMW Four Cylinder Engine

The 316ti and 318ti models of new BMW 3 Series compact saw BMW deploy the new generation of four-cylinder engines with their 1.8 and 2 litres of displacement, 85 and 105 kW/6,000 (115 and 143 hp) and torque values of 175 and 200 Nm/3,750 respectively. The defining feature of these engines is their unique Valvetronic valve drive system, a throttle-free regulation mechanism with fully variable valve lifts. Combined with double-Vanos, this system makes it possible to attain fully variable control of the valve opening times. Along with this unmatched precision, BMW four-cylinder engines also contain a range of other innovative features such as their four-valve technology, knock control, the plastic intake system and the aluminium crankcase with its open deck construction.
