17201-E0142 | Genuine Hino® Turbocharger J08E For Hino

1. Increase Engine Power

A turbocharger forces more air into the engine’s cylinders.
More air → more oxygen → allows more fuel to burn → more power output.
 Example: A 2.0L turbocharged engine can perform like a 3.0L naturally aspirated engine.

2. Improve Fuel Efficiency

Since the turbo uses exhaust gases (waste energy) to create boost, it makes the engine more efficient.
Manufacturers can use smaller engines that still produce the same power as larger ones, reducing fuel consumption.

3. Reduce Emissions

Better combustion means less unburned fuel and cleaner exhaust gases.
Some modern turbo engines also work well with hybrid systems to further reduce CO₂ emissions.

4. Optimize Engine Size and Weight

A smaller, lighter turbo engine can replace a larger engine, improving vehicle balance and handling while saving space.

1. Loss of Power

• The most obvious sign.

• The car feels sluggish, especially during acceleration.

• You might notice slower turbo “spool-up” or that the boost gauge (if you have one) shows lower pressure than normal.

2. Excessive Exhaust Smoke

• Blue or gray smoke: often means oil is leaking into the exhaust due to worn turbo seals.

• Black smoke: too much fuel and not enough air (turbo not providing enough boost).

• White smoke: could indicate coolant leakage or severe internal damage.

3. Unusual Noises

• Whining, siren-like, or grinding sounds when accelerating — caused by worn or damaged bearings or turbine blades.

• A healthy turbo usually has a smooth “whoosh” or gentle whistle, not a loud screech.

4. Oil Leaks or High Oil Consumption

• A failing turbo can leak oil into the intake or exhaust system.

• Check for oil residue in the turbo housing or around intercooler pipes.

5. Check Engine Light (CEL)

• The engine control unit (ECU) may detect low boost pressure, airflow problems, or sensor errors and trigger a warning light.

6. Poor Fuel Economy

• If the turbo isn’t compressing air properly, combustion becomes less efficient, and the engine uses more fuel.

7. Boost Pressure Problems

• On turbo gauge–equipped cars, you may notice no boost, low boost, or fluctuating boost pressure — all signs of internal damage or leaks.
