ALL YOU NEED TO KNOW IN THE SERVICE AND REPAIR OF YOUR ENGINE


B6 ENGINE:

In Japan, the United Kingdom, and Australia a fuel-injected version called the B6F was available. Kia's version of the B6 had a marginally shorter stroke (at 83.4 mm), for a total displacement of 1,594 cc. This engine was used in the Rio, Sephia II, and Shuma.

This engine was dubbed BP-ZE and featured a forged crankshaft, piston oil squirters, a structural aluminum oil pan with cooling fins, a 7,000 rpm redline, and the Variable Inertia Charging System (VICS).
