Fuel System

The engine’s fuel system is designed to create a better combustion process, making the car more fuel-efficient while reducing noise and emissions.

Lubricant Module

The machine’s Lubricant Module filters and cools the engine, and monitors its temperature. This makes servicing much easier for professionals who work on trucks as their job!


The most powerful and efficient engine in its class, the Torque Mx-13 produces 1.55 to 2 tons per liter of torque with peak values at low RPM for better acceleration response when you need it most!


Fuel Injection System

Compacted Graphite Iron

They say that the key to happiness is balance, and for these guys. The engine of their vehicles is built with 75% stronger CGI, which makes them 20% lighter than gray cast iron!


Electronic Control Module

As the brain of the PX-9, the ECM accurately controls all engine functions for optimum performance and fuel economy.

Heavy-Duty Design

The PX-9’s heavy-duty design extends engine life and protects engine components by lowering internal temperatures with targeted piston cooling and a bypass oil filtration system.

When your truck engine needs a Replacement?

If your car has engine trouble, you need to decide whether to repair the engine or replace it.

Engine failure is often due to a cracked engine block and must be replaced rather than repaired.


Keeping your car’s engine cool is critical for protecting it, so follow all manufacturer guidelines on required maintenance.

Improper Engine Lubrication

Lubrication protects the engine’s moving parts from damage and wear. If there’s low oil pressure or contaminated fuel, the car will fail because of it!

Knocking noises

When your engine knocks, the sound is typically caused by an air-fuel mixture that has not been fixed or can be a sign of major damage.

Loss of performance

If your car doesn’t accelerate when you drive it, there is not enough fuel in the tank, or the engine isn’t working.

Here are a few reasons the engine loses its performance:

  • Low compression will lead to a sluggish engine. Diagnosing the problem is usually the next step before getting a repair.
  • If there is a malfunction with the camshaft position sensor, the car will not function properly.

Car Exhaust Smoke Colors

You might be able to pinpoint the problem with your car by looking at what comes out of its tailpipe. If you see colorful smoke, that means there’s some issue and probably not just an oil change!

Does Smoke Color Identifies Car’s Health?

Knowing the colors of smoke can help you diagnose your car’s issue quickly and get it repaired faster.

White Smoke (It is Normal)

The water vapor in your car’s exhaust is what makes white smoke when it starts to warm up. It can be seen most clearly on a cold day, but you might also notice this if there are light clouds during sunset or sunrise because condensation builds up inside an engine compartment!

Blue Or Gray Exhaust Smoke (Isn’t Considered Normal)

The color of your exhaust smoke is telling you something. There’s a good chance it has an oil leak, and the engine is burning fat with excessive consumption! You may need professional help for this problem- different causes like broken valve seals or damaged piston rings can cause these types of issues as well…

Black Exhaust Smoke (Something Serious)

The car may be giving off black exhaust smoke, which could mean it has an issue with its fuel system. A clogged air filter can harm your gas mileage and reduce performance, so make sure to have any problems inspected by a professional before they worsen!

Persistent, Milky White/gray Exhaust Smoke (Serious)

If you see thick white/gray exhaust smoke pouring from your car’s tailpipe, this could be an indication that there is a cracked block or cylinder head. Both of these problems are highly detrimental and must be addressed immediately!
