We’ve just released a new version of our GTC605, and it contains many improvements, focused on ease-of-use, accuracy, and reliability. As was the case with our GTC505 redevelopment, the re-design was prompted by our inability to purchase the NXP Kinetis processors that we were using for the previous version. The changes to the Fuel Injection […]

Mechanical Diesels are tough to diagnose, and very few tools help with it. The GTC605 helped us repair this small, old, unevenly-timed Yanmar 2GM. This 1984 Yanmar 2GM is a 40-year-old two cylinder indirect injection Diesel engine with jerk-type injectors. This type of small twin generally runs a bit rough because the timing is uneven (180-540 degrees), which tends to mask minor issues, but the GTC605 helped us uncover the problems.

Diesel engines are notoriously smoky, producing much more blue, white, and black smoke than their gasoline-powered counterparts. The fundamental reasons for this are that diesels operate at higher pressures, with lower-purity fuel, and variable fuel-air ratios. This post covers the different types of smoke, and their (complicated) causes.
