Professional Engine Rebuilding May Offer a Simpler, Lower Cost Way to Cut Greenhouse Gas Emissions
Several plans are currently being debated in the public forum in an attempt to find a way to reduce greenhouse gas emissions. Most of these concepts have been debated for years – setting higher mileage standards, implementing advanced technologies, and passing “cash for clunkers” legislation. The head of one of the country’s largest engine parts distribution groups says one simple, quicker and less costly idea is starting to gain more attention – professionally rebuilding worn-out and inefficient engines of the millions of older cars and trucks now on the road.

Emissions Update: Understanding How Wide Ratio Air/Fuel (WRAF) Sensors Work
Instead of giving a simple rich/lean indication, wide ratio air/fuel sensors measure the “actual” air/fuel ratio. A WRAF sensor can measure mixtures that range from extremely rich to extremely lean (even straight air!). This ability allows the PCM to control fuel mixtures much more precisely, to handle much leaner fuel mixtures, to reduce emissions and
‘Sensing’ Problems: A Drop in Fuel Economy and Higher Exhaust Emissions Signal O2 Sensor Replacement
Oxygen sensors have been used for more than a quarter of a century, dating back to 1980 when the first computerized engine control systems appeared. Part of the fuel management system, the oxygen (O2) sensor monitors unburned oxygen in the exhaust. The powertrain control module (PCM) uses this information to determine if the fuel mixture
