HYBRID ENGINE (PETROL + AIR)

ABSTRACT

The commercial vehicle is required recently to change the power sources and materials for every part of the vehicle more ecological and for any environmental problem such as CO2 Emission and air pollution.
The compressed air vehicle (CAV) has been studied for several years, but it seems difficult at this moment to complete with a commercial vehicle which uses fossil fuel to get a dynamic performance such as acceleration and running range. Hence the HYBRID ENGINE with a petrol and compressed air is considered. The analysis of how the hybrid Engine runs and its efficiency are carried out by Performance Test and Exhaust Test.
The hybrid engine concept is used to design an air engine and petrol engine to provide the torque to Compressor tank. In order to make this system possible for a compressed air based vehicle, the NONC SWITCH and TIMER CIRCUIT are connected with compressor tank. Air engine, Petrol engine and Air compressor are connected in parallelly.


Problem Summary

In Summary, it indicates that Hybrid Engine:  (A) has a positive effect on environment and will increase the efficiency of vehicle, and (B) It can also operate in petrol-engine-only mode, or petrol and air in combination. The work presented is of both experimental and theoretical nature with the aim to illustrate the compressed air is also useful to drive the vehicle with the combination of petrol.
Hybrid Engine is a promising concept with the possibility to reduce vehicle fuel consumption as well as exhaust emissions. The advantages with hybrid engine (Petrol + Air) compared to the electric hybrid are first and foremost simplicity combined with a great potential for cost reduction. Initial testing of hybrid engine modes of operation was conducted.
In spite of the existence of servel techniques like Hybrid engine which is the combination of Petrol and Electric, the proposed design of Hybrid engine which is the combination of Petrol and Air remain the most effective. Indeed, although the capital cost is more as compare to other engine.

Detailed Description Problem

Hybrid engines are generally equipped with at least two prime movers capable of developing mechanical power. One prime mover can be a thermal engine such as an internal combustion engine, although it is conceivable that the vehicle could be equipped with a gas turbine or a steam engine. This engine generates mechanical power from the combustion of a hydro-carbon fuel. The second prime mover frequently is a dual function system that can either develop mechanical work or can convert applied mechanical work to a form which can be stored. One source of mechanical work subject to conversion for storage can be vehicle kinetic energy captured during braking (regenerative braking) Another source can be the thermal engine being operated to supply mechanical work to the second prime mover.
Air Engine can readily function in the role of the second prime mover. The hybrid system combines a conventional petrol engine and automatic gearbox with a hydraulic pump and motor that is powered by compressed air. The Hybrid system can operate in zero emissions air mode, where compressed air is used to drive the hydraulic motor, which then turns the transmission and thus the front wheels.
In a parallel hybrid engine, the single electric motor and the internal combustion engine are installed such that they can power the vehicle either individually or together. Most commonly the internal combustion engine, the electric motor and gear box are coupled by automatically controlled clutches. For electric driving the clutch between the internal combustion engine is open while the clutch to the gear box is engaged. While in combustion mode the engine and motor run at the same speed. The Air tank is supported by an air compressor which may be coupled directly to the internal combustion engine for operation.
Air suspension systems often provide for automatic leveling of the vehicle. When a vehicle equipped for automatic leveling is in the Power take off mode of operation (Petrol engine not running), the chassis’s position and loading in relation to a suspension level sensor system can change. Outriggers may be deployed changing the local loading on the individual air springs. Even without outriggers the load carried by each wheel of the vehicle can be affected by use of the Power take of application. Under these circumstances the level sensor system can cause the air suspension system to inflate. However, in trying to level the vehicle, the air suspension leveling system can be more useful to the vehicle's supply of compressed air as compare with petrol.
Under non-hybrid engine applications this inflation and deflation process is of little consequence because the Petrol engine is running and typically provides ample surplus power at near idle operation to turn the chassis's air compressor and thereby maintain sufficient air pressure and volume for proper suspension. However, in the case of the hybrid engine mode of operation, once the primary air pressure begins, the petrol supply will be stop.
Other Hybrid Systems can be present on vehicles including pneumatically system, Gasoline and Electric system, Gasoline and compressed natural gas system and the like. Similarly the operation of these systems can deplete the compressed air charge stored on the vehicle affecting the operation of the hybrid Petrol and Air system actuated.
 

EXPECTED OUTCOMES

The expected benefits of the project is to be carried out using the new hybrid engine concept, Project will accrue to consumers, firms, and in all level of internal combustion engine through an improved understanding of the operation and performance of Air engine and Petrol Engine combination system. Areas of hybrid engine concept emphasis are the impacts of changes in strategies, technologies, consumer behavior, and policies on the economic performance of the recently available system, and economic analysis of private and public strategies that affect improvement in Vehicle and other quality attributes. The procedures for the hybrid engine project emphasize understanding of the operation of the Petrol and Air combination system, and analysis of its performance. Compressed Air is more useful than Petrol is the keystone of the Project. End goal of this work is to provide road maps of recently available option to run the vehicle and consequences.
In the next two years, Peugeot Citroen will make new petrol-air hybrid car. Currently he is working on his project. The benefits of this improved understanding will principally be felt in improved private and public decision making and improved performance of the system.
