ECway Technologies provides engineering projects and software development with offices in multiple cities in India. They specialize in the design and fabrication of flexible fuel vehicles (FFVs) that can run on gasoline blended with ethanol or methanol. FFVs have engines that can burn varying proportions of these fuel blends through automatic adjustment of fuel injection and spark timing. The document then provides details on the working principle of two-stroke engines and lists advantages of using liquefied petroleum gas (LPG) in dual fuel vehicles such as lower costs, reduced emissions, and extended engine life compared to gasoline.

DESIGN AND FABRICATION OF FLEXIBLE FUEL VEHICLE
Synopsis
A flexible-fuel
Generator
(FFV) or dual-fuel
vehicle
(colloquially called a flex-fuel vehicle) is an alternative fuel vehicle with
a internal combustion engine designed to run on more than one fuel,
usually gasoline blended with either ethanol or methanol fuel, and both fuels are
stored in the same common tank. Flex-fuel engines are capable of burning any
proportion of the resulting blend in the combustion chamber as fuel
injection and spark timing are adjusted automatically according to the actual
blend detected by electronic sensors. Flex-fuel vehicles are distinguished
from bi-fuel vehicles, where two fuels are stored in separate tanks and the
engine runs on one fuel at a time, for example, compressed natural
gas (CNG), liquefied petroleum gas (LPG), or hydrogen.
Working principle
A two-stroke engine is a combustion engine that completes the thermodynamic
cycle in two movements of the piston compared to twice that number for a fourstroke engine. This increased efficiency is accomplished by using the beginning
of the compression stroke and the end of the combustion stroke to perform
simultaneously the intake and exhaust (or scavenging) functions. In this way
2. two-stroke engines often provide strikingly high specific power. Petrol (spark
ignition) versions are particularly useful in lightweight (portable) applications

Advantages
LPG is cheaper than petrol (up to 50%)
It produces less exhaust emissions than petrol
It is better for the engine and it can prolong engine life
In some vehicles, it can provide better performance
Has a higher octane rating than petrol (108 compared to 91)
Disadvantages
It has a lower energy density than petrol
