True or False: Offset DI can be less expensive but may create uneven piston crown temperatures and thrust loads.

The statement is true because using offset Direct Injection (DI) can indeed lead to cost savings in manufacturing and fuel efficiency, as it allows for more strategic placement of fuel injectors. However, this design choice can result in uneven temperatures on the piston crown. As the injectors spray fuel at an angle rather than directly on the piston’s surface, the mixture may not heat evenly, which can cause hot spots or cooler areas on the piston.

In addition, uneven distribution of fuel can affect how forces are applied to the piston during combustion. This imbalance can create varying thrust loads on the piston, potentially leading to increased wear and tear over time. Therefore, offset DI's design can lead to beneficial cost reductions but also introduces risks regarding engine performance and durability, particularly in terms of thermal efficiency and mechanical integrity.
