Question

Quizplus · Accepted Answer

Multivalve engines do allow for more complete combustion due to increased air flow and better fuel distribution, which is what Technician A suggests. Technician B is also correct in stating that the benefits of multivalve engines can be offset by the complexity of their camshaft arrangements, which can make them more complicated and potentially more expensive to manufacture and maintain.
