Automobile engine variants and price discrimination
Using a structural model of demand for automobile engine variants, this paper finds that there is second-degree price discrimination: markups increase with engine size. Still, average markups are lower than when models have just one engine. The paper develops the first empirical demand framework suitable for markets with variants. There is an unobserved product characteristic and a consumer-spe...
متن کاملSound Radiation Analysis of Automobile Engine Covers
A methodology to study the sound radiation of engine valve covers is presented. The analysis process uses a nonlinear static simulation followed by a steady state dynamics simulation to determine the sound pressure field due to the vibration of the engine cover. The effects of assembly loads are included. The methodology is demonstrated with two representative engine valve covers using acoustic...
متن کاملRehabilitation for improving automobile driving after stroke.
BACKGROUND Interventions to improve driving ability after stroke, including driving simulation and retraining visual skills, have limited evaluation of their effectiveness to guide policy and practice. OBJECTIVES To determine whether any intervention, with the specific aim of maximising driving skills, improves the driving performance of people after stroke. SEARCH METHODS We searched the C...
متن کاملDyamic analysis of balancing of an automobile engine using ADAMS
Abstract—This paper explain the primary balancing of single cylinder engine and optimizing the counter balancing mass to reduce the unbalanced forces coming on the crankshaft. After optimizing, the effect of primary balancing is validated. After primary balancing, the vibration is measured on the engine at various locations. Balancer shaft is designed for the unbalanced forces exist after prima...
متن کاملFPGA-Based Cooling Fan Control System for Automobile Engine
In this paper FPGA is used as the master chip to design the new fourphase sensorless BLDC(brushless direct current) motor control system of automobile engine cooling fan. The design uses BEMF zero-crossing detection algorithm and the hardware modular design approach, while the open-loop circuit adopted to raise the frequency and voltage and the digital phase-shift circuit based on FIPS algorith...
