More Causes of Engine Trouble in Large Vehicles
Engine trouble in large vehicles is a major issue that should be addressed promptly whenever possible.
As we discussed previously, large vehicles are the backbone of many different industries. Unfortunately, they are not immune to the typical problems that frequently plague motor vehicles. Among these, engine trouble is one of the most difficult issues to deal with. Engines in large vehicles are highly complex, which makes issues more difficult to diagnose and repair. That’s why it’s best to have a reliable repair shop you trust to inspect and maintain your vehicle regularly. This will keep you from having to deal with unexpected engine trouble while you’re out on the road. In this blog, we discuss just a couple of the causes of engine trouble in large vehicles, along with how to deal with them.
Exhaust System Issues
The exhaust system plays a critical role in managing emissions and maintaining engine performance. Common exhaust-related problems in large vehicles include:
- Exhaust Leaks: Cracks or holes in the exhaust manifold, pipes, or muffler can lead to exhaust leaks, which can affect engine performance and increase emissions.
- Clogged Diesel Particulate Filter (DPF): In diesel-powered vehicles, the DPF captures soot and other particulates from the exhaust. Over time, the filter can become clogged, leading to reduced engine power and increased emissions.
- Catalytic Converter Problems: The catalytic converter helps reduce harmful emissions. A failing catalytic converter can lead to increased pollution and may trigger warning lights on the dashboard.
Diagnosis and Repair: Exhaust system issues are typically diagnosed through visual inspection, exhaust gas analysis, and diagnostic codes from the ECU. Repairs may include replacing damaged components, cleaning or regenerating the DPF, or replacing the catalytic converter.
Lubrication System Failures
Proper lubrication is essential for the smooth operation of an engine. Without adequate lubrication, engine components can experience excessive wear, leading to severe damage. Common lubrication-related issues include:
- Oil Leaks: Oil leaks can occur from various points in the engine, including the oil pan, valve cover gaskets, and seals. Low oil levels can lead to insufficient lubrication and increased engine wear.
- Oil Pump Failure: The oil pump is responsible for circulating oil throughout the engine. A failing oil pump can lead to low oil pressure, causing engine components to wear out faster.
- Contaminated Oil: Over time, engine oil can become contaminated with dirt, metal particles, and other debris. Contaminated oil can lead to sludge buildup and reduced lubrication efficiency.
Diagnosis and Repair: Lubrication issues are diagnosed by checking oil levels, oil pressure, and inspecting for leaks. Technicians may also perform an oil analysis to check for contamination. Repairs may involve fixing leaks, replacing the oil pump, or changing the oil and filters.
