With a total of four patents to his name, Lancaster stands out for his innovative contributions to automotive technology. His recent work addresses key issues in engine efficiency and performance.

Latest Patents

Among his latest patents, Lancaster has developed an engine vacuum enhancement system that includes a manifold absolute pressure (MAP) module. This system compares the MAP of an engine to a predetermined value, enabling the control system to adjust air flow and ignition timing effectively. When the MAP exceeds the predetermined level, the air/spark module reduces air flow and advances the ignition spark, optimizing engine operation.

Additionally, Lancaster invented a method and apparatus for reducing engine torque disturbances during start-up. This innovative solution draws down intake manifold pressure before cranking the engine, mitigating torsional disturbances. In a preferred design, he integrates a secondary air injection reaction pump to effectively evacuate the intake manifold, achieving the desired pressure reduction.
