2. 3 and 4-cylinder comparison
Today, the 4-cylinder engine is the most widespread. In recent years, however, demand for a new generation of economical engines has grown. So it seemed natural to think of the 3-cylinder engine, especially as it can be derived directly from a 4-cylinder already in the range. We're going to compare these two types of engine, limiting ourselves of course to the aspects directly linked to acycling, the heart of this article's subject.
2.1 Instantaneous torque comparison
Figure 15 shows instantaneous torque comparisons for 3 and 4-cylinder engines at two specific speeds: 2,000 rpm -1 and 5,600 rpm -1...
