MECHANICS & REPAIR SHOPS

Supporting Diesel Professionals
Since 1983.

When a diesel-powered vehicle or piece of equipment enters your shop with poor performance, excessive smoke, reduced fuel economy, plugged filters, injector problems, or hard starting, the cause isn't always a failed component.

Fuel quality, contamination, injector deposits, and inefficient combustion can all contribute to diesel performance problems.

DSG Power Systems helps mechanics and repair facilities take a more complete approach to diesel diagnostics with fuel system expertise, professional repair services, clean fuel solutions, diesel parts, and 4+ Fuel Additives.

Fuel Problems Can Look Like Mechanical Problems

Modern diesel fuel systems operate under demanding conditions and rely on precise fuel delivery. When fuel quality deteriorates or contaminants enter the system, the resulting symptoms can easily become a repair-shop problem.

Understanding what is happening upstream of the engine can help technicians identify underlying causes and reduce the likelihood of repeat problems.

Injector Deposits

Deposits within diesel injectors can interfere with proper fuel atomization and spray patterns, contributing to inefficient combustion, reduced performance, increased fuel consumption, and other drivability concerns.

Water & Contamination

Water, sediment, rust, microbial contamination, and other contaminants can accumulate in stored diesel fuel and eventually reach equipment fuel systems.

The result can include prematurely plugged filters, corrosion, injector problems, restricted fuel flow, and unexpected downtime.

Fuel Stability

Diesel fuel can change during storage, particularly when equipment or bulk fuel remains unused for extended periods.

Maintaining fuel quality and addressing contamination before it reaches sensitive fuel-system components can help prevent unnecessary repairs.

Poor Combustion

When injectors cannot deliver fuel correctly, combustion quality can suffer. Customers may experience reduced power, poor fuel economy, smoke, increased emissions, or other performance concerns that ultimately bring the equipment into your shop.

The Role of Multi-functional Diesel Fuel Additives

Multi-functional diesel fuel additives can provide repair shops with another tool for addressing and preventing common diesel fuel-system concerns.

Depending on the application and formulation, additives can help support:

Detergent technology can help clean and control deposits that interfere with proper injector operation and fuel atomization.

Additional lubricity can help protect sensitive fuel-system components against wear.

Maintaining fuel quality can be particularly important for seasonal equipment, generators, stored vehicles, and other applications where diesel remains in storage for extended periods.

Corrosion inhibitors can provide additional protection for fuel-system components exposed to moisture and challenging operating conditions.

Maintaining clean injectors and proper fuel delivery helps support more complete and efficient combustion.

A Complete Approach To Diesel Fuel System Problems

DIAGNOSE

Identify the Source of the Problem

Testing fuel-system components and evaluating fuel condition can help separate mechanical failures from contamination, deposits, or fuel-quality concerns.

REPAIR

Restore Proper Operation

Address worn, damaged, contaminated, or malfunctioning fuel-system components with the appropriate repair, replacement, or calibration.

CLEAN

Address Contamination Upstream

Fuel filtration, polishing, water removal, and tank maintenance can help prevent contaminated stored fuel from immediately reintroducing problems.

PROTECT

Help Prevent The Problem From Returning

Proper filtration, preventative maintenance, clean fuel practices, and multi-functional fuel additives can help maintain fuel-system cleanliness and performance.

Did You Know?

Replacing a damaged fuel-system component may solve the immediate problem, but contaminated fuel can put the replacement component right back at risk.

Go Beyond Replacing Parts

For repair facilities, solving the immediate mechanical problem is only part of the equation. Identifying why the component failed or became compromised can help prevent the same problem from returning. A complete fuel-system approach can include:

Evaluate injectors, pumps, fuel delivery components, filtration, and fuel quality to help identify the underlying source of a diesel performance problem.

Testing and servicing diesel injectors and fuel-system components can help determine whether performance issues originate from mechanical failure, deposits, contamination, or another fuel-related concern.

Multi-functional diesel fuel additives can support injector cleanliness, fuel stability, lubricity, corrosion protection, and combustion performance as part of a preventative maintenance strategy.

When contamination originates upstream, treating the engine alone may not solve the entire problem. Fuel testing, filtration, water removal, fuel polishing, and proper storage practices can help address contamination before clean fuel reaches the equipment.
