Emissions 101: A Basic Understanding Of How Catalytic Converters Operate

To begin, an internal combustion engine creates heat energy by igniting a mixture of gasoline and atmospheric oxygen with a high-voltage spark.

Toyota To Reduce Emissions From North American Operations By Up To 40%

Toyota Motor North America (TMNA) is committing to aggressively reduce its carbon output in the United States by entering into Virtual Power Purchase Agreements (VPPAs).

ASA Opposes Pennsylvania Vehicle Emissions Modification Bills

Four Republican Pennsylvania senators, Sens. Judith Ward, Elder Vogel, Patrick Stefano and Wayne Langerholc, have introduced a quartet of bills aimed at modifying Pennsylvania’s vehicle emissions and maintenance program.

EGR And Secondary Air Injection And Emissions Management

The perfect internal combustion vehicle would be able to put the exact amount of fuel and air into the combustion chamber. If the perfect combustion event were to occur, you would get nothing more than water and carbon dioxide as byproduct. There would not be any unburned fuel or oxygen. Combustion would occur at the right temperature so oxides would not combine with nitrogen and carbon to form nitric oxides (NOx) and carbon monoxide (CO). This perfect car would not need a catalytic converter or any other emission-control device.

BorgWarner Innovation Helps Hybrids Improve Fuel Efficiency And Reduce Emissions

By using the heat from exhaust gas, which would normally be diverted through the exhaust pipes and wasted, the company’s technology reduces engine warm-up time, enhances efficiency, and significantly improves fuel economy and reduces emissions.

Ford Hits CO2 Manufacturing Emissions Reduction Target 8 Years Early

The company had a global reduction of manufacturing CO2 emissions of more than 3.4 metric tons from 2010 to 2017 – equivalent to greenhouse gas emissions from more than 728,000 passenger vehicles driven for one year.

OBD II Emissions Monitors

OBD II is primarily emissions-driven and will set codes anytime a vehicle has a fault that may cause emissions to exceed federal limits by 1.5 times. It doesn’t necessarily mean the vehicle has a real emissions problem. Many times it does not. But, if the nature of the failure is such that it might cause emissions to rise, OBD II will set a code anyway. That is why some states are allowing motorists to opt for a second-chance tailpipe test if their vehicle fails an OBD II test. In many instances, the vehicle will pass the tailpipe test.

Tenneco Expands Walker Emissions Control Coverage By More Than 100M Vehicle Service Opportunities

The expanded Walker offering also now includes exclusive aftermarket catalytic converter coverage for more than 26.6 million light trucks and SUVs certified to the U.S. LEV1 SULEV classification.

Evaporative Vapor Emissions Control

These EVAP monitors can be run in two different ways. Ford, GM and some Asian imports use a vacuum to run the monitor. Chrysler, most European and a few Asian products use pressure to run the monitors.
