Diesel particulate filter

When someone mentions diesel, many people still have the image of a loud and obnoxious machine that is hard to start in the cold weather. This may have been true twenty to thirty years ago, but could not be further from the truth today! With all of the advancements in engine and emissions technology; diesel has become the new standard in fuel economy and power while still maintaining strict pollution standards as mandated by the EPA. As C.J. Baker explained here, “Diesel development has come a long

explosion by forcing the exhaust gases out of the cylinder, drawing in air (or fuel-air mixture in non-diesel engines), and compressing the air or fuel-air mixture before the fuel is ignited. Fig 1. Working of four stroke engine. There are several differences between diesel engines and non-diesel engines. Nondiesel engines combine a fuel mist with air before the mixture is taken into the cylinder, while diesel engines inject

Highly porous ceramics (foams, honeycombs, fibres , mats, etc.) find numerous applications in various engineering fields, including filtration (molten metals, particulate from diesel exhaust gases), radiant burners, catalyst supports, biomedical devices, kiln furniture, reinforcement for metal matrix composites, bioreactors, thermal protection systems, supports for space mirrors, components in solid oxide fuel cells, lightweight sandwich structures, heat exchangers (graphite foams), etc. Talking

INTRODUCTION CRDi stands for Common Rail Direct Injection meaning, direct injection of the fuel into the cylinders of a diesel engine via a single, common line, called the common rail which is connected to all the fuel injectors. Whereas ordinary diesel direct fuel-injection systems have to build up pressure anew for each and every injection cycle, the new common rail (line) engines maintain constant pressure regardless of the injection sequence. This pressure

Winter is a time of fun in the snow, hot chocolate, and resting by a warm fire. It is also a time for viruses to run a muck. The following are a few tips to help keep the cold and flu bugs at bey. 1. Wash your hands frequently. This is a commonly known virus fighter. Anything we touch has been touched by others who might be carrying a virus. Frequent hand washing can keep us from allowing these germs to enter our bodies. 2. Crack a window in your house for a few hours a day. One of the reasons

This report comprises the Emissions Inventory of Stationary Sources for the United States Army Garrison-Kwajalein Atoll (USAG-KA). The report was prepared according to Section 3-1.11.3 of the USAKA Environmental Standards (UES) to update the inventory of stationary sources of air pollutants following issuance of a DEP-13-002.0, Construction and Operation of Space Fence Radar System. As appropriate for the additional new sources this update contains the appropriate information as required by Section

Why Diesels Are Greener Than We Think This paper is not intended to condemn hybrid engines, as they can be good engines and a practical means for vehicle manufactures to power their products or meet emissions. This is to present the idea that gasoline hybrid engines are inferior to Diesel engines. I concede that a Diesel hybrid engine would be more beneficial in some applications. Ideally, we need to come up with better road systems and better road surfaces. If the roads are better maintained

Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletiondue to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems. Indoor

Are EPA Diesel Emission regulations regulating Truck owners? As a result of EPA regulations, today’s diesel engines are more efficient than ever before seen in large and midsized trucks. Certain regulations restrict truck owners from using certain truck models, because of excess diesel emission. Increasing drastically as technology improves, cars and trucks produce less and less diesel exhausts and emissions. “But because diesel engines can operate for 30 years or more, millions of older, dirtier

spend as little time as possible outside (e.g., in your yard or balcony) close to a construction site during operation time. Additionally, having a rich vegetation around your home (and between the home and the construction site) will act as a natural filter for the generated pollution, reducing the amount of pollution you may come in contact with. So, planting in your yards or even pot plants in a balcony can help. The greener the better. Also, regular spraying of water around the home will reduce the
