Fuel effects on driveability and hydrocarbon emissions of spark-ignition engines during starting and warm-up processes
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 1997.

Active driveline and suspension control to improve vehicle handling
… The control objectives are to both improve the driveability of the vehicle and ensure the stability. The driveability is measured by the ability to track a linear reference yaw rate. This aims to linearise the yaw rate response to the steering input and gives the driver predictable handling. …

Assessing the hydrocarbon emissions in a homogeneous direct injection spark ignited engine
… research gasoline, and a fuel with a high driveability index (DI), i.e. a less volatile fuel. The results showed less-than intuitive results for the response of HC to varying coolant temperature and varying injection pressure. For the coolant temperature data, the deviation from intuition …

Design and control of a robotic thumb using piezoelectric actuators
… (PZT) actuators exhibit a high back driveability which could facilitate this compromise. Although they have low displacement and force output, they are useful in fine control applications. When combined with a DC motor, PZT actuators can produce precise, delicate movements in robotic …

An improved powertrain attributes development process with the use of design structure matrix
… attributes of Shift Quality, Performance Feel, Driveability, and Trailer Towing. Engineering work to achieve specific attributes is currently handled attribute by attribute and the system is brought together later. This lack of a more holistic view results in a large amount of engineering rework …

Effect of fuel properties on the first cycle fuel delivery in a Port Fuel Injected Spark Ignition Engine
… PFI engine. Four fuels between 1083 and 1257 Driveability Index (DI) were tested, and the fuel delivery results have been correlated to properties of the ASTM distillation curve. The fractional distillation point that correlates to fuel delivery is a function of temperature - at colder …

A Laboratory and Field Study of Composite Piles for Bridge Substructures
… FRP composite piles, (3) evaluate the driveability and the axial and lateral load behavior of concrete-filled FRP composite piles, steel-reinforced recycled plastic composite piles, and prestressed concrete piles through field tests and analyses, and (4) design and implement a long-term …

Modellbasierte Optimierung des Betriebsverhaltens eines Kegel-Ring-Getriebes in einem Kraftfahrzeug
This thesis describes the most important processes for the development of a Prototype Control System for vehicle application of the cone ring transmission. Based on a model of the cone ring transmission, it was possible to develop a closed loop control for the ratio adjustment, and also to test the …
