[0026] It should be noted that the V-type engine body is divided into two structural forms: one with a step at the bottom and one without a step at the bottom. Take the 240 engine body and the 280 engine body as examples. Figure 1 As shown, the V-shaped 240 machine body is a machine body structure without steps, while the V-shaped 280 machine body is a machine body structure with steps.
