ACERT Technology Explained
ACERT stands for Advanced Combustion Emission Reduction Technology. It’s Caterpillar’s proprietary multi-system emissions approach that combines high-pressure common rail fuel injection, advanced air management (twin turbochargers in some variants), aftertreatment systems including DPF and SCR (where applicable), and CAT ECM controls. ACERT was Caterpillar’s path to meeting EPA Tier 4 emissions without re-architecting the base engine, which is why the C13 ACERT retains the proven C13 architecture while adding modern emissions compliance.
Signs You Need a Replacement C13 ACERT
- Loss of compression on one or more cylinders during dyno or in-frame test
- Cylinder head crack symptoms (coolant loss, white smoke, hard start)
- Excessive blowby past piston rings (sign of bore wear or ring failure)
- Connecting rod or main bearing knock under load
- Oil consumption above factory spec for the engine’s age
- ECM diagnostic codes pointing to internal mechanical issues
- Aftertreatment failure that has damaged the engine (DPF clog with backpressure damage, etc.)
- Donor truck or equipment has been totaled or sold for parts and the engine is being moved to a new chassis
- Repower of a Class 8 truck, construction excavator, generator, or marine vessel that originally received its C13 ACERT from new
Known Cat C13 ACERT Issues We Inspect Before Shipping
