Report on the Latest Improvements in Internal Combustion Engines

This report delves into the latest improvements in internal combustion engines (IC engines), focusing on technological advancements and design considerations. It highlights the incorporation of green technologies, such as regenerative braking systems and the use of biofuels, to enhance fuel efficiency and reduce environmental impact. The report also examines the perspective of fleet managers, emphasizing the importance of fuel economy, vehicle selection, and maintenance costs. The discussion covers strategies like higher compression ratios and the reduction of parasitic losses to optimize engine performance. Additionally, it touches upon the utilization of advanced biofuels, such as hydrotreated vegetable oils, to increase fuel blends. Overall, the report provides insights into current trends and future directions in IC engine development, catering to the needs of students studying mechanical engineering and related fields.

LATEST
IMPROVEMENT ON
INTERNAL
COMBUSTION
ENGINE

• From a combustion point of view, there are technologies which
enables us to operate it as close to the stoichiometric air: fuel
ratio as possible without the requirement of fuel enrichment to
control the temperature of the exhaust.
• So many scientist have tried to do the improvement of the I.C
engines to enable co0me up with almost an ideal engine.
• Some of these improvement for the level 3 college leaners
includes the following.

1. Designing with Green in Mind
• The application of brake energy has been incorporated in
both diesel engine for vehicles and gasoline engines for the
automaker’s dynamic technology platform.
• The battery of the vehicle is charged when the automobile
is decelerating or coasting.
• The condition of the battery’s charge will be continually
checked and the alternator is detached at any time when the
battery is fully charge and the automobile will hence
accelerate.

• There is no technology which is the best solution for all users.
• Even though the urban users will benefit from reformative only
braking and electric driving. For suburban and extra urban users
diesel ICE and advanced gasoline are the best options.
• During the design of the I.C engine is advisable to select the best
vehicle for fuel costs, each application, energy costs required to
be carefully scrutinized.
• Therefore when such an engines are being manufactured the
designers must take into consideration of all these factors.

• Many gasoline engines are manufactured to operate on the
green fuels like biofuels.
• This will include the mixing of the fuel technologies. This
technology supports advanced biofuels of the second generation
like hydrotreated vegetable oils this could be employed to
upsurge the blend of the fuel to 25 %.
• The biodiesel engine will actually help in the conservation of
the environment and makes the combustion of the fuel greener.

2. Approaching It from a Fleet Point of view
• For fleet managers, enhancements to the I.C engine will be to their benefit,
particularly on improving resale and keeping costs down.
• A fleet manager must take into consideration the big picture of not only the
maintenance costs but also the real-world fuel economy.
• It is advisable to match your automobile choice to the certainties of your
fleet.

• That is why persistent improving our mastery of the internal
combustion engine is obviously the smartest move for the
predictable future.
• When Mazda observed ways to reinvent its version of the I.C
engine, it considered at two key areas: ensuring all that power got
to the wheels and capturing more of the energy released when the
fuel is burned .

• The most obvious way which can be done is through higher
compression ratios and battling parasitic losses in every
part of the car.
• Whereas Toyota strategies to propose fleet managers a
multilayered automobile posing that then can be employed
in their regional locations to take a good benefit of the local
energy sources and automobile working requirements.
