ENGINE PROBLEMS

Engine performance can be affected in a number of ways, from corrosion of metal parts to excess cylinder friction. And one of the most common causes of decreased performance is fuel itself. Even high-quality fuel can leave behind carbon deposits that build up on key engine parts, causing problems that range from reduced horsepower to poor fuel economy.

FUEL SYSTEM

Fuel systems have come a long way in the past century, but an inefficient fuel system can still be tremendously frustrating. When fuel leaves behind carbon deposits and ethanol draws water into the fuel system, performance, fuel economy and an engine’s longevity can all suffer.

FUEL INJECTORS

Fuel injectors are a key component in delivering the right amount of gasoline to the combustion chamber. Poor fuel injector performance results in hard starts, power loss, rough idling, reduced fuel economy and increased emissions.

CARBON BUILDUP

Clogged Fuel Injector
Clean Fuel Injector

Fuel injectors increase fuel efficiency and engine response times by delivering a fine mist of fuel right at the engine’s intake valves. This allows fuel to burn more easily, increasing the engine’s response times while reducing the amount of fuel used. Port fuel injectors spray fuel in the intake port area where it flows past the intake valve into the combustion chamber. Direct injectors have the tip positioned directly in the combustion chamber and spray fuel into the combustion chamber, bypassing the intake valve. This design allows the engine to have even better fuel economy. Carbon deposits can clog fuel injectors, turning the fuel pattern into a stream instead of a mist. As a result, less fuel is delivered to the combustion chamber and the fuel that does enter the chamber burns less efficiently.

PERFORMANCE ISSUES

Hard starts, power loss, rough idle, slow acceleration, lower fuel economy, increased emissions.

SOLUTION

Gumout® fuel additives use a variety of detergents to fight carbon buildup in fuel injectors. These detergents bond to carbon particles on injectors and disperse them to restore performance. They also bond to the surface of the nozzle, helping prevent further carbon buildup.

Port fuel injectors can be cleaned using a detergent called PIBA (polyisobutylene-amine). But GDI/direct injectors are harder to clean. They require P.E.A. (polyether-amine), a specialized detergent that’s strong enough to survive the heat of a combustion chamber. Check individual product details for detergents used. Port fuel injectors spray fuel in the intake port area where it flows past the intake valve into the combustion chamber. Direct injectors have the tip positioned directly in the combustion chamber and spray fuel into the combustion chamber by-passing the intake valve. This design allows the engine to have even better fuel economy.

INTAKE VALVES & PORTS

Intake valves regulate the delivery of fuel and air into the combustion chamber. In a port-injected engine, air travels down the port and mixes with fuel from the injector, spraying onto the intake valve which opens into the combustion chamber. In a direct-injected engine, air only travels past the intake valve and then mixes with fuel in the combustion chamber.

MORE ABOUT INTAKE VALVES & PORTS

CARBON BUILDUP

Carbon buildup on intake valves, before and after.

Fuel and carbon deposits on the valves negatively affect acceleration, causing hesitation. And when carbon deposits build up on the base of valves, they act like sponges, soaking up fuel. This means less fuel than expected enters the combustion chamber, disrupting the fuel-air mix and hurting performance

PERFORMANCE ISSUES

Rough idle, hesitation, surging, increased emissions.

SOLUTION

The detergents in Gumout fuel additives bond to carbon deposits on intake valves and ports to disperse them, restoring performance. They also bond to the metal surfaces of the valves and ports to help prevent future carbon buildup.

Next: COMBUSTION

COMBUSTION

The combustion chamber is the most unforgiving environment in the engine. With temperatures as high as 495° F, it’s the most difficult part of the engine to clean. Carbon buildup on piston tops and cylinder heads can create hot spots, leading to preignition, loss of performance and potentially severe engine damage.

Piston Tops

Piston tops are subjected to massive amounts of pressure and heat during the combustion process. When deposits form, they cause hot spots that ignite fuel before spark ignition. The resulting noise is knocking and pinging caused by this pre-ignition. This causes the piston to be pre-maturely pushed down in the cylinder when the crankshaft is trying to push it up. This can lead to parts damage and head gasket failure.

Engines generate power by igniting a precise fuel-air mixture in the combustion chamber. The fuel and air are heated through compression, then ignited with a spark plug for a controlled explosion. Carbon deposits on piston tops and cylinder heads trap heat, creating hot spots that can cause fuel to ignite prematurely. These uncontrolled ignitions create higher pressures than normal combustion and can cause knocking, pinging and, in extreme conditions, engine damage.

PERFORMANCE ISSUES

Preignition, increased emissions, engine failure.

SOLUTION

Gumout® fuel additives use P.E.A. (polyether-amine) to remove deposits from difficult-to-clean parts like combustion chambers, piston tops and cylinder heads. While most detergents burn up in the heat of the combustion chamber, P.E.A. remains stable, even at 495° F. It bonds to carbon deposits and removes them from the fuel system. P.E.A. also bonds to metal surfaces to prevent future buildup.

Cylinder Heads

When running smoothly, cylinder heads allow fuel/air mixture and exhaust to flow smoothly into and out of the combustion chambers. But when deposits form, they can cause a disruption of the air-fuel mixture, leading to inefficient combustion and lost performance.

MORE ABOUT CYLINDER HEADS

CARBON BUILDUP

These deposits negatively affect the flow of the atomized air-fuel mixture as they enter into the combustion chamber. This can cause inefficient combustion leading to reduced engine performance.

PERFORMANCE ISSUES

Power loss, lower fuel economy.

SOLUTION

Gumout® fuel additives that have P.E.A. (polyether-amine) in their formulas help to remove deposits from difficult-to-clean cylinder heads. While most detergents burn up in the heat of the combustion chamber, P.E.A. remains stable, even at 495° F. It bonds to carbon deposits and removes them from the fuel system. P.E.A. also bonds to cylinder head surfaces to help prevent future buildup.

Engine Fluids

An engine’s fluids interact with it’s metal surfaces, often under extreme conditions.

OIL

Oil is the lifeblood of the engine, working to lubricate parts, dissipate head and remove contaminants. And as an engine ages, these functions become even more important. Excessive heat or humidity in the oil system accelerates the breakdown of oil, creating a layer of sludge on engine parts.

OIL SYSTEM

Oil Sludge Buildup – Before
Oil Sludge Buildup – After

When sheared past its limitations, oil will not deliver the lubrication needed to keep the engine from overheating or potentially causing complete failure. The oil system literally and figuratively keeps things running smoothly. Metal engine parts interacting with each other work more efficiently when properly lubricated with clean oil. Oil filters can only do so much, so when the extreme conditions of the engine take their toll on oil, it can lose viscosity, decreasing its ability to lubricate. Dirty oil can cause sludge and acid buildup, which can damage key engine parts. When sheared past its limitations, oil will not deliver the lubrication to keep the engine from overheating or potentially completely failing.

PERFORMANCE ISSUES

Dirty oil can cause sludge build up that can reduce performance and increase wear. Acid build up leads to corrosion that can damage engine parts. The second paragraph needs to be tailored to MSTU not high mileage oil treatment which we haven’t sold in years. So detergency and anti-corrosion should be the main talking points – clean oil lubricates better reducing heat that can cause parts damage and reduced sludge allows parts to move more freely increasing performance. Cleaning agents found in MSTU help keep engine oil and parts clean to unleash your engines full potential and corrosion inhibitors ensure that you maximize engine life.

SOLUTION

Gumout High Mileage Oil Treatment removes sludge and deposits using specialized cleaning agents to help restore performance and extend the life of engine parts. Gumout additives also recondition worn seals to prevent leaks, while viscosity improvers work to increase oil pressure, reducing blow-by and oil consumption. To protect the valve train from wear and corrosion, the ZDDP (zinc dialkyl dithiophosphate) in Gumout adheres to metal surfaces, forming a protective layer against friction and corrosion to keep the engine running longer and smoother.

FUEL

The same fuel you put into your vehicle to make it run is also slowly killing it. Fuel – even top-tier gasoline with added detergents – leaves behind carbon deposits that bind to engine parts and sap performance and this problem is compounded the longer the engine is not run.
There are also other enemies of your engine that can not only hinder optimal engine operation, but can actually damage your engine: water and cold temperatures.

MORE ABOUT FUEL

PERFORMANCE ISSUES

Humidity and condensation can also cause water to build up in the fuel system over time. This effect is amplified by gasoline blended with ethanol, which attracts water, especially in hot, humid climates. In colder climates, water makes any gasoline in the fuel line more susceptible to freezing and damaging engine parts. Ice in the fuel line can block fuel flow, preventing the engine from running. The detergents in Gumout remove water from the fuel system, improving fuel quality and performance. Diesel fuels can also lead to issues in colder climates. Unlike gasoline, ultra-low sulfur diesel fuel has a relatively high pour point. This is due to naturally occurring waxes in the fuel that start to crystalize as they dip below 20°F, depending on the specific fuel. When the waxes start to freeze, it can cause the fuel to gel.

SOLUTION

In engines that aren’t used frequently, both gasoline and diesel fuel can deteriorate, leaving behind varnish and gummy carbon residue. Gumout Multi-System Tune-Up stabilizes fuel and oil using an antioxidant to stop deterioration and extend the life of fuel, allowing engines to start easier and run smoother after sitting unused. The detergents in Gumout remove water from the fuel system, improving fuel quality and performance. In addition, Gumout Multi-System Tune-Up contains isopropyl alcohol, which grabs even more water, scavenging condensation to keep it from freezing in winter or corroding metal engine parts. Gumout diesel additives use an anti-gel compound to counteract the effects of crystallization and improve cold flow.
