The N45 MSS X in-line 4 cylinder at 99 hp and N67 MNT X in-line 6 cylinder at 175 hp are geared for mining applications due to their clean and quiet performance.  Enhanced by extremely low ventilation rates, (4,000 and 6,500 cfm respectively) these me-chanical engines are more economical and more productive for day to day underground operations. “We use the N45 primarily for service vehicles and personnel carriers. Initial start up on the engines and long term service has been flawless.  The engine is extremely smooth with no excessive vibrations or noise,” said Jeff Clinton, Wallace Diesel Mining Equipment.
