They found that total particulate gravimetric mass collected over the engine test cycle was more than 2 times higher for B0 than for B20 fuel. We are unaware of previous studies reporting this type of comparison of the exhaust PM. In the experiments, they used a 4-cylinder, 1.9-liter In vitro and in vivo responses to PM.

With lower exhaust heat, heat efficiency was enhanced, and consequently, fuel efficiency was enhanced as well. The electrically driven water pump allows coolant flow rate to be controlled with greater precision based on vehicle conditions for better fuel efficiency. Eco mode maximizes fuel savings across all driving conditions.
