lpc abbreviation in lpc2148

LPC is a family of 32-bit microcontroller integrated circuits by NXP Semiconductors (formerly Philips Semiconductors). The LPC chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0. Internally, each microcontroller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals. The earliest LPC series were based on the Intel 8-bit 80C51 core. As of February 2011, ....etc

ELECTRO HYDRAULIC CAMLESS ENGINE
WORKING OF CAM ENGINES
Crank shaft turn the cam shaft
Cam lobe pushes down the pushrod and it opens the valve
Return motion is carried out due to spring action on push rod
This results in closing of the valve
(Animation)
Back
WHY camless engines ?
Infinitely variable valve timing.
More torque is made available throughout the rev-range.
Increases durability and engine life .
Valve train weight which limits the rotational speed ....etc

ABSRACT
HCCI has characteristics of the two most popular forms of combustion used in IC engines: homogeneous charge spark ignition (gasoline engines) and stratified charge compression ignition (diesel engines). As in homogeneous charge spark ignition, the fuel and oxidizer are mixed together. However, rather than using an electric discharge to ignite a portion of the mixture, the concentration and temperature of the mixture are raised by compression until the entire mixture reacts spontaneously. Stratified charge compres ....etc

ME Engines the New Generation of Diesel Engines

INTRODUCTION

The introduction of the electronically controlled camshaft-less low speed diesel engines, which is now gaining momentum, is a milestone in diesel technology that deserves a place in history like Rudolf Diesel s first engine in Augsburg, the 1912 motor vessel Selandia, the introduction of turbocharging on two-stroke diesels in 1954, and the first SCR (Selective Catalytic NOx Reduction) systems on ships in 1989. This paper will outline how MAN B&W takes a ....etc

CAMLESS ENGINES A NEW APPROACH IN I.C.ENGINES
internal combustion comprise the valve train hardware . In the camless valvetrain, the valve motion is controlled directly by a valve actuator there's no camshaft or connecting mechanisms. Various studies have shown that a camless valve train can eliminate many otherwise necessary engine design trade-offs.Automotive engines equipped with camless valvetrains of the electrohydraulic and electro-mechanical type have been studied for over twenty years, but produc ....etc

Project on CAMLESS ENGINES


Introduction

CAMS
Control the breathing channels (valves) of an IC engine
Connected to camshaft which is operated by crankshaft
Cams push open valves at proper time & guide their closure
But they are inflexible except VTEC & VVT-I
Engineers could not vary timing, lift & duration of valve opening infinitely.

Working of conventional engines

The crankshaft turns camshaft which operates valves by mechanism as in figure
Spring brings back valve to initial posi ....etc
