An HCCI engine is a type of internal combustion engine that uses compression ignition where the fuel and air uniformly mix and ignite automatically without a spark plug. In an HCCI engine, the fuel and air are compressed to a point that causes autoignition, resulting in more complete combustion than traditional engines. HCCI engines can achieve up to 15% fuel savings compared to traditional engines due to lower emissions and peak combustion temperatures. However, HCCI engines are more difficult to control and can experience higher cylinder pressures that may damage the engine. Major automakers are investing in HCCI research as it shows promise for improved fuel efficiency.

History of gasoline direct compression ignition (gdci) engine a review
Abstract The first single-cylinder gasoline direct compression ignition (GDCI) engine was designed and built in 2010 by Delphi Companyfor testing performance, emissions and Brake specific fuel consumption (BSFC). Then after achieving the good results in performance, emissions and BSFCfrom single-cylinder engine, multi-cylinder GDCI engine was built in 2013. The compression ignition engine has limitations such as high noise, weight, PM and NOX emissions compared to gasoline engine. But the high efficiency, torque and better fuel economy of compression ignition engine are the reasons of Delphi Company to use compression ignition strategy for building a new combustion system. The objective of the present review study involves the reasons of building of the GDCI engine in detail. Keywords: Delphi Company,Emissions, Multi-Cylinder GDCI engine andSingle-CylinderGDCI Engine.

Converting a Diesel Engine to Dual-Fuel Engine Using Natural Gas
Over the past many years, large numbers of car buyers have been opting for a petrol car with a compressed natural gas (CNG)
kit fitted by the company. The most important thing is that the petrol engines cause global warming by having a large amount
of toxic gases exhausted by the petrol cars. However, by the introduction of catalytic converters (a catalytic converter is a
vehicle emissions control device that converts toxic pollutants in exhaust gas to less toxic pollutants by catalysing a redox
reaction) we have been able to reduce the toxic emissions. Use of Catalytic converters in internal combustion engines fuelled
by either petrol or diesel, which reduces pollutants such as CO to a much less harmful gas, such as CO2. Because of this, a
catalyst car also consumes slightly more fuel, thus reducing its performance. However, by having these improvements, petrol
engine cars with catalysts still exhaust more CO and HC than cars with diesel engine, and by using a CNG kit there is are other
problem such as starting problems and jerks. Therefore, CNG kit is not as useful as it is expected to be. An alternative to this is
a diesel engine (dual fuel engine). However, a question arises that, Why Should one Choose a Diesel Powered dual fuel Engine
over other. So the answer is Diesel fuel contains more energy per litre than petrol. Thus, making more efficient than petrol
engine car. Diesel fuel contains no emissions of the regulated pollutants like (carbon monoxide, hydrocarbons and nitrogen
oxides) which are quite less than those from petrol cars without a catalyst. Therefore, diesel engines are attracting greater
attention due to higher efficiency and cost effectiveness. Now, the main objective of this paper is to convert a diesel engine into
duel fuel engine with compressed natural gas, which will overcome the problem of cost and global warming. This paper
presents a dual fuel system for diesel-natural gas operation for a diesel engine, and analysis of the operating characteristics of
the engine.

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
