Additional Physical Format: Online version: Allsup, J.R. Emission characteristics of propane as automotive fuel. [Washington, D.C.]: U.S. Dept. of Interior, Bureau. The objective of the study was to evaluate engine parameters relating to the advantageous use of propane as a low-pollution fuel.
Some comparisons are made between gasoline, natural gas, and propane. Results show that engines can operate over a wider range of a/f with minimum carbon monoxide and hydrocarbon emission when using propane than when using gasoline. Emission characteristics of propane as automotive fuel / By J.
Allsup, Ralph David Fleming, Bartlesville Energy Research Center., National LP-Gas Association (U.S.). For various fuel-air mixtures and different compression ratios, the intake temperature was varied over the entire range of ***°F (K) down to − °F (K) when employing a single cylinder spark ignited research engine fuelled with natural by: Propane fuel has a lower carbon content than conventional gasoline and diesel fuel.
When used as a vehicle fuel, propane can offer life cycle greenhouse (GHG) emissions benefits over conventional fuels, depending on vehicle type, age, and drive cycle. Increasingly stringent emissions regulations have led to the development of improved emissions control systems in conventional light- medium- and.
HC and CO emission resulting from co-burning of LPG with diesel, the HC and CO emission of the dual fuel engine were still lower than those of gasoline engine.

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 . 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 .
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.

Figure 1: Greenhouse Gas emissions of various fuels The use of LPG as an alternative fuel for gasoline has been studied extensively in recent years.
This paper represents an detailed theoretical investigation on the performance and emission characteristics of SI engine fueled with LPG at different operating parameters and operating conditions. Differences in the power producing capacities and exhaust emission characteristics of various spark-ignition-engine fuels are frequently obscured by interactions involving the particular engine system used in the comparison.

In an attempt to minimize this problem, gasoline, propane, methane, and a hCited by: GHG emissions from a life cycle perspective.
A transportation mode may have relatively few GHG emissions from the vehicle itself, but emissions could be higher from the production of the fuel. Greenhouse Gases Included The greenhouse gases CO 2, CH 4, and N 2 O are emitted during the combustion of fuels in mobile sources.
For most. background. Diesel engines due to the better fuel economy have been widely used in automotive area. However, the limited reserve of fossil fuel and deteriorating environment have made scientists seek to alternative fuels for diesel while keeping the high efficiency of diesel by: 2.
Hear from a district that has been using propane buses for 35 years and is currently saving $ million on fuel annually. Great for the District and Kids School officials explain why the savings, quieter operation, and decreased emissions of propane buses are better for their district and students alike.
The impact of fuel switching on emissions depends upon its duration and certain vehicle characteristics, but emission increases of percent for HCs and percent for CO can easily occur (Greco ~.
1) Three different air-fuel mixtures have been used for propane fuel (C 3 H 8), to evaluate the amount of emissions produced in mole fraction from combustion process for this fuel. First mixture was lean, (f = ), second one was stoichiometry, (f = ), and the third mixture was rich, (f = ).Author: Ali S.
