GASOLINE ENGINE
TECHNOLOGY
EXPLAINED
Innospec has created Dynamico, a new range of fuel additive technology specifically designed to combat the deposit build up within a GDi engine. Dynamico not only cleans up existing deposition within one tank of fuel, it also protects the engine from further deposition.

GDI
Due to the pressures on OEMs to reduce emissions, Gasoline Direct Injection (GDi) engines have been designed and are present in many of the vehicles we see on the roads today.
GDi engines work by injecting fuel directly into the combustion chamber which brings efficiencies by being able to deliver more power and performance whilst being able to reduce engine size. Utilisation of these engines has reduced fuel consumption compared to their predecessors, the Port Fuel Injection (PFI) gasoline engine.
These engines rely on maintaining their efficiency by ensuring an optimum spray pattern of fuel delivered by the injector. Unfortunately, using fuel without specific GDi additive technology increases the potential of deposits to be formed on the fuel injector. These deposits can disrupt the spray pattern which results in an increase in fuel consumption, emissions and a risk of injector failure.
Innospec has created Dynamico, a new range of fuel additive technology specifically designed to combat the deposit build up within a GDi engine. Dynamico not only cleans up existing deposition within one tank of fuel, it also protects the engine from further deposition.
This ensures that a GDi engine is working at its optimal efficiency. Dynamico unlocks the full potential of GDi to offer the benefits of increased fuel efficiency, consistent power output and optimum reliability as well as lower CO2 emissions. Dynamico is able to ensure that these engines perform as they were designed to allow a true balance between reducing emissions and performance.
PFI
GDi engines entered the market to replace Port Fuel Injection (PFI) gasoline engines due to their benefits in increased efficiency. These older types of gasoline engines work by injecting fuel into the air intake manifold so that the fuel mixes with the combustion air prior to entry into the combustion chamber.
Due to the difference in design of these engines, the deposition build-up occurs on the inlet valve prior to the combustion zone and is referred to as inlet valve deposits or IVD.
Any deposits formed in an engine's fuel system are detrimental to performance and the build-up of IVD is no different. Inlet valve deposits can disrupt the flow of the air fuel mixture causing a loss of engine efficiency. In extreme cases, these deposits can also affect the valve from seating and therefore a loss of pressure in the combustion chamber.
This reduced pressure results in less power, poor driveability and increased fuel consumption.
When Innospec created Dynamico, we recognised complete performance was needed in all gasoline vehicles in the market. Dynamico will clean and protect both GDi and PFI vehicles from all fuel system deposits.
Complete performance
Dynamico is a range of gasoline fuel additives that offers complete performance for all gasoline engines. By using Dynamico technology within your fuel, all the benefits of Precision, Performance and Protection will ensure that your vehicle is performing at optimum efficiency regardless of the type of engine technology.
