The B-series features engine bores machined directly into the block (rather than the wet liners used on earlier Cummins engines). It is also set apart by the use of a shallow one-piece head, requiring closer tolerances than in other Cummins products. Unlike other diesel engines of the time; the B-series Cummins used direct … Nettet3. jun. 2015 · Pistons move up and down in the cylinders of the block because a mixture of fuel and air is ignited within the cylinder.
