Importance of maintenance, diagnosis and Servicing

intake systems

Objectives: At the end of this lesson you shall be able to
• explain Importance of maintenance
• diagnosis faults in Intakes System
• demonstrate servicing of Intake system.

• Air intakes system: In engine air is drawn into the cylinder from atmosphere through air cleaner, turbocharger,
induction manifold, intake port and inlet valve. The induction manifold provides passage for the flow of fresh air
from air cleaner via turbo charger towards the engine cylinder. The intake valve provides entrance for the fresh
air charge into the combustion chamber and cylinder. The following air flow system is used in diesel induction
system.
Air cleaner → Turbo charger → Induction manifold → Intake port → Inlet value → Combustion chamber and
cylinder
• Importance of maintenance of system: Maintaining the air intake system is crucial for optimal performance
and efficiency. Regularly inspect and clean air filters to ensure proper airflow and prevent any kinds of
damages. Check for any leaks or damage in the intake ducts and hoses is ensure that the system as good
condition. Additionally, schedule periodic inspections to address any issues promptly and keep the system
running smoothly.
Importance of diagnosis of system

1 Performance Optimization:
Identifying problems early can prevent decreased engine performance and fuel efficiency.
2 Prevent Damage
Finding issues like clogged filters or leaks early can prevent damage to the engine and other system
components.
3 Cost Savings
Finding problems before big damaged it’s can save money by preventing more significant repairs down the
line.
4 Emissions Control
A faulty air intake system can be responsible for increased emissions, affecting environment. We can stop it
by solving problems.
5 Safety
Ensuring proper air intake is important for engine combustion and overall vehicle safety.
6 Long lifespan
Regular diagnosis and maintenance can extend the lifespan of the engine and related components, reducing
the need for repair and replacements.
Importance of servicing of system
regular servicing of the air intake system is essential for maintaining vehicle performance, efficiency, reliability,
and safety.
Engine performance: A clean and properly functioning air intake system ensures the engine receives the right
amount of air for combustion, optimizing performance and power output.

Fuel efficiency: A well-maintained air intake system helps achieve efficient fuel combustion, leading to better fuel
economy and reduced fuel consumption.
Emissions control: Proper air intake system servicing contributes to lower emissions by ensuring optimal air-to-
fuel ratios, helping vehicles meet environmental regulations and reducing their carbon footprint.
