Fuel injection systems for light vehicles (SI) in the Ecuadorian market. Study case: Japanese brands

Abstract

Internal combustion engines are a major source of environmental pollution and depletion of fossil resources. To address these problems, different technologies such as gasoline direct injection (GDI) have been developed, which reduce emissions and improve engine efficiency. This work is oriented towards the analysis of the types of fuel injection systems incorporated in the spark ignition engines in Japanese brand vehicles that are offered in the Ecuadorian market during the year 2023 and the fuel quality requirements. The technological method was used considering the practical approach, with two stages: bibliographic collection and data collection and processing. There are 5 Japanese brands in Ecuador, corresponding to the third  place in vehicles according to country of origin, with a total offer of 31 models, also constituting 25% of vehicles in Ecuador's automotive fleet. The Mazda brand includes direct injection systems in all its models, at the same time requiring Super premium fuel for operation, in the remaining brands they combine direct and indirect injection systems in the models for sale. This segment of brands offers 50% of models with direct injection, this technology being growing in vehicles of Japanese origin in the Ecuadorian market.
