Opel 4-valve engines turn 100

A century ago, Opel has launched for the first time that four-valve per cylinder engine in the 1913 Grand Prix Car. This was the beginning of the way for the series of four-valve engines that are currently more present than ever in the lineup of the brand. The models built for the Grand Prix came with a new 4-cylinder engine that has a displacement of 4.5 liters capable of generating 110 horsepower. The model also came with two intake valves and two exhaust valves per cylinder. This was the first time for Opel to develop the first internal combustion engine that came with 4-valves per cylinder. As mentioned before, everything started back in 1914 when the concept was developed into the 12.3-liter Opel Rennwagen which was known by a lot of people as the green Monster. The 4-valves per cylinder engine was capable of generating up to 260 horsepower which enabled the car to accelerate and reach a top speed of 228 km/h. Engines with 4-valves per cylinder were only in fashion again thanks to racing and this happened in the late 1950s. The specialists had problems with the development of the models as the process was too slow. The first model to hide it under its hood was the Opel Ascona in 1979, which came with a 2.4-liter engine capable of generating 140 horsepower, 100 horsepower less than the rally car it was based on. Even so, the model was capable of accelerating from 0 to 100 km/h in 7.6 seconds and to reach a top speed of 200 km/h. The first volume model was the Kadett GSi 16V which was produced in 1988. This model was powered by a 2.0-liter 16V engine capable of generating 150 horsepower and 196 Nm of torque. Please enjoy the photo gallery we have prepared below.
