Propane and the Environment. Refined fuels and petroleum products are perceived as pollutants and environmentally unfriendly. Propane is not only clean and environmentally friendly in its unused state, it produces exhaust emissions that exceed the requirements for clean fuel vehicles and surpass eco-friendly expectations in all aspects.

Propane vehicles have been widely used and refined for decades. There are two types of propane vehicles: dedicated and bi-fuel. Dedicated propane vehicles are designed to run only on propane, while bi-fuel propane vehicles have two separate fueling systems that enable the vehicle to use either propane or gasoline.

Liquefied Petroleum Gas Combustion General1 Liquefied petroleum gas (LPG or LP-gas) consists of propane, propylene, butane, and butylenes; the product used for domestic heating is composed primarily of propane. This gas, obtained mostly from gas wells (but also, to a lesser extent, as a refinery by-product) is stored as a liquid under.

Designed specifically to correlate with the NATEF program, and updated throughout to correlate to the latest NATEF and ASE tasks, Automotive Fuel and Emissions Control Systems, 4/e combines topics in engine performance (ASE A8 content area) with topics covered in the advanced engine performance (L1) ASE test content area.

The result is cost-efficient, easy-to-learn-from resource for 4/5(6). Emissions from fuel oil combustion depend on the grade and composition of the fuel, the type and size of the boiler, the firing and loading practices used, and the level of equipment maintenance.

Because the combustion characteristics of distillate and residual oils are different, their combustion can produce significantly different emissions.

Cost-effective engines: Automotive-style, spark-ignited engines are readily available in high volumes, making them more economical than similarly sized diesel and propane engines.

Liquefied petroleum gas or liquid petroleum gas (LPG or LP gas), is a flammable mixture of hydrocarbon gases used as fuel in heating appliances, cooking equipment, and vehicles. It is increasingly used as an aerosol propellant and a refrigerant, replacing chlorofluorocarbons in an effort to reduce damage to the ozone specifically used as a vehicle fuel it is often referred to as.

In this study, a spark ignition engine operated with DME-blended LPG fuel was studied experimentally. In particular, the effect of n-Butane and propane on performance, emissions characteristics (including hydrocarbon, CO, and NOx), and the combustion stability of an SI engine fuelled with DME-blended LPG fuel were by: The objective of this work was in brief to discuss conventional micro-pilot injected dual-fuel combustion and in detail to explain about PREMIER combustion and emission characteristics in a pilot ignited supercharged dual-fuel engine fueled with natural gas and syngas, and to study the effect of H 2 and CO 2 content in syngas on the combustion and emission formation over the broad range of Cited by: 5.

EPA’s Approach. EPA regulates the emissions from mobile sources by setting standards for the specific pollutants being emitted. EPA established progressively more stringent emission standards for carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter, starting in the mids for on-road vehicles and in the early s for nonroad engines and equipment.

The effect of accidental fires are simulated to understand the response of items such as vehicles, fuel tanks, and military ordnance and to remediate the effects through re-design of the items or changes in operational procedures. The comparative combustion emissions of using jet propellant (JP-5) liquid fuel pools or a propane manifold grid to simulate the effects of accidental fires was Cited by: 1.

Fuel Economy. Federal regulations also mandate automotive fuel economy. The period from to resulted in primary emphasis on emission control with loss of fuel economy from lower compression ratios, changes in spark timing, A/F ratio and axle ratio changes, and exhaust gas.

The composition of NG, which is mainly methane, has significant effects on engine performance and emissions [8]. High Wobbe number which reflects high hydrocarbon content results in higher power density, better fuel economy, lower CO 2, CO and HC but higher NO X emissions [6].

In this study, a spark ignition engine operated with DME-blended LPG fuel was studied experimentally. In particular, the effect of n-Butane and propane on performance, emissions characteristics. In this paper, the effects of fuel injection timing on fuel consumption, combustion, and emission characteristics fueled with diesel and diesel−propane blends in a single-cylinder diesel engine were investigated.
