Homogeneous Charge Compression Ignition Market Size
and Analysis – Forecast to 2025
Homogeneous Charge Compression Ignition (HCCI) market refers to the engine ignition
which is the combination of Spark Ignition (Otto-Engine or SI-Engine) and Compression
Ignition (Diesel Engine). The process utilizes homogeneous fuel-air mixtures similar to the
SI-engine and uses high compression ratio for mixture to auto-ignite similar to the diesel
engine. This lean homogeneous mixture reduces particulate emissions and helps
auto-ignition, reducing the overall emission of NOx to about 90-98%. The engine is featured
to offer an increased fuel efficiency of over 15-30%, compared to the SI engines.

HCCI engines compatibility with alternative fuels is anticipated to garner high growth
prospects for the industry over the next few years
Owing to its compatibility with alternative fuels that specifically include gasoline and diesel,
is encouraging more automakers to invest in the technology. Moreover, industry participants
are increasingly focusing on integrating fuels with high octane and cetane number to enhance
the reliability and durability of the engines. In conjunction with the increasing versatility and
compatibility, the popularity of these engines will increase during the projected period. Some
of the major initiatives by the automotive industry participants are mentioned below:
In 2011, BMW introduced its new B-family engines featuring three-, four- and six-cylinder
diesel and petrol which commercialized in 2014. These were designed to accommodate next
generation technology that included HCCI and hybridization.
U.S. DoE and Bosch
Bosch announced its leading participation in Advanced Combustion Controls - Enabling
Systems and Solutions (ACCESS) that was US$ 12 Mn project funded by U.S. Department of
Energy (DoE). The project involved exploration of HCCI as a part of the project to develop
advanced light duty petrol engine.
Mercedes-Benz showcased F700 sedan, featuring fuel saving technology such as VVC,
ISAG, and mild hybridization. The technology showcase emphasized on an estimated fuel
saving of up to 47.5% in comparison to its S350 model. Moreover, the company
spokesperson was reported to state the company was making significant efforts in three to six
modular inline engines with variable compression ratio and HCCI technologies
As of the news statement made by Delphi in May 2016, the company is making significant
efforts in the development of Gasoline Direct Compression Injection engine on similar
concepts. Utilizing the tight charge stratification and low temperature combustion, the
prototypes four-cylinder engine registered 13-18% fuel economy gain. The company is
planning to commercialize the technology by the mid-2020s.
General Motors, Honda, Hyundai, Mazda, Volkswagen are few of the other major vendors
that have also made significant progress and are likely to introduce the models featuring this
technology. This increased participation of the OEMs and the vendors have led to increased
emphasis on the exploration of the technology. These initiatives will present significant
growth prospects for the future growth through the forecast period.
Some of the major drawbacks in the current development of the technology include:
● Increased refinement of control strategies is required to assure fuel economy
under practical driving conditions and standard production tolerances
● NOx emissions have to stay low enough within the standardized driving cycle.
Deployment of additional De-NOx components or technology would deteriorate the
fuel economy and associated costs. Moreover, confirmation for the feasibility of
three-way catalyst only technology for Euro 6 under production conditions is still
● In conjunction with the appropriate variable lift systems, the requirement of the
fastacting variable cam-phaser is yet another factor hampering the growth prospec​t
● NVH control requirement specifically for the normal SI modes and HCCI/CAI
operation transitions in order to enhance the customers’ acceptance
These are the major issues constraining the adoption of these equipment, are expected to be
major growth challenge to the HCCI market. It is expected that these challenges will certainly
be met upon the commercialization of the technology.
Increasing demands to curb the carbon emissions and enhance the fuel economies by
Department of Transport (DoT) and EPA in U.S. and EU in Europe are expected to
prominently drive the innovation in the industry through the forecast period.
