In this work, pentanol and camphor blended with petrol in different proportions were used on spark-ignition engines to evaluate their performance, characteristics, emissions. Sample P0A (gasoline) showed the best specific fuel consumption for lower torque (3Nm) a value of 19.2Kg/kWh, sample P0B (100% pure gasoline 5% camphor) had higher (6Nm) 12.9Kg/Kwh. For brake thermal efficiency, gives effi...

Modern engines have an increasing number of control parameters that are having a dramatic impact on calibration time. Up-front prototyping of calibration processes can be used to reduce the burden of increasing powertrain complexity, however, such techniques are still in their infancy in the automotive field. In this paper we illustrate how flexible model-based calibration tools can be used to ...

This paper presents experimental test results of a new compressed natural gas direct injection (CNG-DI) engine that has been developed from modification of a multi cylinder gasoline port injection (PI) engine. The major modifications done are (1) the injection system has been modified to gas direct injection using new high pressure gas injectors, (2) compression ratio has been changed from 10 t...

In this contribution, the investigation conducted on alternative fuels includes methanol 20% blended with gasoline 80% and emulsion-based fuel composition of 80%, ethanol 15%, H2O 5% are compared 100% conventional fuel. These fueled single-cylinders spark ignition engine is studied for checking their performance emission characteristics as per future norms. This work performed One-dimensional A...

It is accepted that the activity of the vehicle pedals (i.e., throttle, brake, clutch) reflects the driver's behavior, which is at least partially related to the fuel consumption and vehicle pollutant emissions. This paper presents a solution to estimate the driver activity regardless of the type, model, and year of fabrication of the vehicle. The solution is based on an alternative sensor syst...

Presenting the influence of compressed natural gas (CNG) used as alternative fuel on combustion an automotive diesel engine represents main objective this paper. The paper studies brake specific energetic consumption, in-cylinder pressure and rise rate, carbon dioxide, nitrogen oxides, smoke hydrocarbons emissions at 2000 rev/min 40%, 55% 70% load. Low content will determine lower CO 2 all load...

The emissions from direct injection (DI) diesel engines remain a serious setback the viewpoint of environmental pollution, especially for those who have been persuaded to use biofuel as an alternative fuel. main drawbacks using biofuels and their mixtures in DI are increased decreased brake thermal efficiency (BTE) compared neat current study analyses biodiesel made cashew nut shell liquid (CNS...

This research presents effect of triacetin and ethanol as additive to biodiesel (Neem oil methyl ester) on the performance and emission characteristics of a diesel engine at different loads and constant engine speed. Compared with biodiesel, slightly lower brake specific energy consumption for triacetin and ethanol bended fuels was observed. At higher engine loads CO,HC and smoke emission were ...

The quest for alternatefuels for a CI engine has become all the more imperative considering its importance in the economy of a nation and from the standpoint of preserving the environment. Reported in this paper are the combustion performance and P-θ characteristics of a CI engine operating on B20 biodiesel fuel derived from Jatropha oil.Itis observed that the twin effect of advancing the injec...

Biodiesels, which are made from various crops, as well as animal fat, are renewable, bio-degradable, and non-toxic and are eco-friendly compared with fossil fuels. Currently, there are more than 350 oil-bearing crops identified as potential sources for biodiesel production. In this study, the potential of biodiesel obtained from a non-edible oil source (Moringa oleifera) was explored and compar...
