Question 1

Why can’t the engine use 100% natural gas?

Dedicated natural gas engines have very high operating temperatures (approximately 650℃), which require high-temp parts and are well above the operating temperatures of a diesel engine. To preserve the freedom of choice of operating in either a dual fuel mode or a diesel only mode, the maximum amount of natural gas needs to be carefully monitored and controlled to operate within OEM temperature and pressure specifications.
