(Ball park numbers - I don't care enough to get real numbers but you get the idea - there is a tiny difference in viscosity between different weight oils at operating temp compared to the viscosity difference between cold and hot oil). A25A-FKS (2.5 D-4S DVVT-iE) - basic engine of the series, transverse, combined injection, DVVT-iE, Miller cycle mode. By 2021, the entire family will have six inline and three V-engines.
#DYNAMIC FORCE ENGINE SERIES#
Most modern engines can only operate at 25-35 thermal. The modern 1.5L 3-cylinder Dynamic Force Engine is the smaller sibling of the 2.0L unit that has already been in production at the same site since. The first engine of the new series under 'Dynamic Force' designation debuted in 2016 (2.5), the second - in 2017 (3.5), the third - in 2018 (2.0). It makes little sense that the oil pump can pump oil that is 100x more viscous when cold but there is some how a problem at operating temperature when the viscosity difference is 5%. Dynamic Force engines achieve increased torque at all engine speeds and promote a 40 thermal efficiency. Now consider the TINY difference that 8, 16, 20, 30, 40, and 50 weight oil represents as far as their differences in viscosity at operating temperature. To achieve engine performance over this speed range, movable engine panels. It's currently being adapted to V-6 and V-8 engines, and it will also spread to trucks and utility vehicles. It starts with a four-cylinder with a displacement of 2.5 liters, which Toyota has now presented in detail at the Vienna Motor Symposium. Over the course of the oil coming to operating temperature, the oil pump MUST be able to pump the oil sufficiently well to satisfy the lubrication demands of the engine. That is, the dynamic force measurements are made simultaneously with two. This engine strategy, dubbed Dynamic Force, will make its way across the lineup. Hondas 1.5 liter turbocharged engine with direct.
Think about the oil pump pumping oil at -20F, 0F, 32F, 50F, 100F, 180F, and operating temperature. The Camry is stocked with a 2.5 liter Dynamic Force engine that gets 29 MPG city and 41 MPG highway. The engines were developed alongside the TNGA family.
The engines can be fueled by petrol (gasoline) or ethanol and can be combined with electric motors in a hybrid drivetrain. I've said this several times although this is admittedly outside my wheelhouse and just I'm thinking this through on a Saturday morning drinking my coffee.Īn oil pump in any vehicle has to be able to pump oil effectively over a HUGE viscosity range. The Dynamic Force engines are a family of internal combustion engines developed by Toyota under the brand's Toyota New Global Architecture (TNGA) strategy.
