Concept
Port Injection
Port injection
is a
fuel delivery system
where fuel is sprayed into the
intake manifold
just before the
intake valve
, allowing for precise control over the
air-fuel mixture
. This method enhances
engine efficiency
and performance by ensuring a more
uniform distribution of fuel
to each cylinder.

Concept
Fuel Injection Systems
Fuel injection systems
are crucial for delivering fuel into an
internal combustion engine
's cylinders in a precise and controlled manner, optimizing performance and
fuel efficiency
. They have largely replaced carburetors in
modern engines
due to their ability to improve
emissions control
and adapt to
varying driving conditions
.
Concept
Intake Manifold
An
intake manifold
is a component in an
internal combustion engine
that distributes the
air-fuel mixture
to the
engine's cylinders
, optimizing
air flow
for
efficient combustion
. Its design significantly impacts
engine performance
, fuel efficiency, and emissions, making it crucial for both naturally aspirated and
turbocharged engines
.
Concept
Air-fuel Ratio
The
air-fuel ratio
(AFR) is a critical parameter in
internal combustion engines
, representing the ratio of air to fuel in the
combustion chamber
. Achieving the
optimal AFR
is essential for maximizing
engine efficiency
, minimizing emissions, and ensuring proper
engine performance
.
Concept
Engine Efficiency
Engine efficiency
is a measure of how effectively an engine converts the
energy stored in fuel
into
useful work
, with
higher efficiency
indicating less
energy wasted as heat
or exhaust. It is crucial for reducing
fuel consumption
and emissions, making it a key focus in both automotive and
industrial applications
.
Concept
Combustion Process
The
combustion process
is a
chemical reaction
between a fuel and an oxidant, typically oxygen, that produces
heat and light
. It is fundamental to
energy production
, transportation, and many
industrial processes
, but also contributes to
environmental pollution
and
greenhouse gas emissions
.
Concept
Electronic Control Unit (ECU)
An
Electronic Control Unit
(ECU) is a crucial component in
modern vehicles
and machinery, acting as the
brain that controls various systems
and functions to ensure
optimal performance
and efficiency. It processes
inputs from sensors
and executes
outputs to actuators
, making
real-time adjustments
based on
programmed algorithms
and data.
Concept
Direct Injection Vs. Port Injection
Concept
Internal Combustion Engine
An
internal combustion engine
is a
heat engine
where the
combustion of a fuel
occurs with an oxidizer in a
combustion chamber
that is an integral part of the
working fluid flow circuit
. This process converts
chemical energy
into
mechanical energy
, making it the
core technology
for powering most vehicles and machinery today.
Concept
Fuel Atomization
Fuel atomization
is the process of breaking
liquid fuel
into
fine droplets
to enhance the
mixing with air
, which is crucial for
efficient combustion
in engines. This process improves
fuel-air mixture homogeneity
, leading to better
combustion efficiency
, reduced emissions, and
increased engine performance
.
Concept
Emissions Control
Emissions control
refers to the
strategies and technologies
used to reduce the
release of pollutants
into the atmosphere from various sources, such as vehicles, industries, and
power plants
. Effective
Emissions control
is crucial for mitigating
air pollution
, protecting
public health
, and addressing
climate change
by limiting
greenhouse gas emissions
.
