Toyota's INSANE NEW Engine SHOCKS The Entire Car Industryįor a little more detail on how Toyota’s Dynamic Force engines perform their combustion magic, here is an Engineering Explained YouTube channel video that offers some very good video graphics on how the aforementioned optimizations physically appear if you were able to view the engine cylinder in cross section during the combustion process. To see how their engine design has evolved from their earliest engines to the modern marvel of today, here is a new video that puts it in the figurative nutshell for car enthusiasts: Optimized thermal management using variable control cooling systems that support optimized combustion with minimal energy loss as heat.Optimizing the airflow tumble into the cylinders by widening the angle between intake and exhaust valves to improve fuel and oxygen mixing for better combustion.Optimizing the stroke to bore ratio by lengthening the stoke and narrowing the cylinders.They achieved this with their modern Dynamic Force Engine by: To achieve improved thermal efficiency, Toyota has modified their engine designs by focusing on how to speed up the combustion process.

For example, Toyota today has reportedly achieved motors with a 41% thermal efficiency-which is a significant achievement when most gasoline engines have efficiencies of roughly 25-33%. The bane of the internal combustion engine (ICE) has always been that from a thermodynamic view…the ICE is very inefficient. Thermal efficiency is the amount of energy produced when a combustion engine burns fuel in relation to the amount of that energy that is converted into mechanical energy. Their Dynamic Force Engine strategy is based on improved thermal efficiency. And that focus has earned Toyota some significant notoriety with their Dynamic Force Engine strategy. Toyota put its focus on making a better engine by improving thermal efficiency which results in increased torque and increased horsepower. But in this case, with automotive engines.

Because the motor is positioned ahead of the transmission, i-Force Max fills in torque dips while the transmission shifts, but Toyota's 10-speed snaps to attention nicely, and it's certainly smoother than the Ford hybrid's 10-speed.While past conversations about Toyota tend to be focused on reliability, ease of repair, and less expensive parts that are easily available, it’s time to take a closer look at how Toyota’s engines have evolved and learn a little about what else makes Toyota a leading automaker. The motor's job is effectively to eliminate turbo lag, which isn't much of an issue in the Tundra to begin with, and once the turbochargers are doing their thing, the electric motor stays mostly dormant. The motor also helps out under sudden full-throttle demands-goosing the accelerator to pass, for example-providing a jolt of juice until the turbos spin up. The electric- and turbo-boost gauges-Toyota didn't fit the Tundra with a traditional power flow gauge, which is too bad-shows that the i-Force Max's electric motor primarily works at low speeds and low rpm, filling in the gap between the driver hitting the accelerator and the turbos building boost. Toyota's engineers told us their goal for the hybrid system was to create a diesel-like torque curve with strong low-end power.
