MMARS - Moon/MArs-base Resource Simulator: A Tool for Generating Quantitative Models of Large Space Projects

1993-07-01
932242
MMARS (Moon/MArs-base Resource Simulator) is a computer program that automatically generates quantitative summaries of the physical resources (components and facilities) required for normal operation of a planned planetary base or other large project. The user enters a small set of base task descriptors which define the goal or purpose of the base, and the program automatically adds all components, facilities, and functions needed to support that task. And because the support components added also generate a need for support themselves (any component may require power, or labor to operate, for example), MMARS continues, in recursive fashion, to add components and facilities to support the growing list of components and facilities, until the demand for new resources no longer increases.

MMC All Aluminum Cylinder Block for High Power SI Engines

2000-03-06
2000-01-1231
An all aluminum cylinder block with a Metal Matrix Composite (MMC) cylinder bore was developed which made it possible to re-design the base engine for high performance with a bore-to-bore distance as narrow as 5.5mm. The cylinder block is an open deck type and the MMC preform consists of alumina-silica fibers and mulite particles. A laminar flow die cast process was selected to ensure defect-free MMC bore quality. To insure good lubrication, electrochemical machining was applied to the bore surface. By use of radioisotope(RI) measurements, MMC reinforcement was optimized for wear characteristics. Particular attention was paid to use of fuels with high sulfur levels.

MMC Pistons a Solution for 1990's High Output Diesels

1989-02-01
890595
A new type of Aluminum piston has been developed to meet the stringent emissions and durability requirements of high output Diesel engines for the 1990's. The successful application of Metal Matrix Composite reinforcements to the superior combination of production squeeze casting and single-axis turning provides a solution for most of the identifiable problems of this class of engines, e.g.- increased peak pressures, improved K factor & improved oil economy. A simultaneous design/manufacturing/quality approach insured the reliability and cost effectiveness of this concept compared with other potential solutions.

MMLV: Aluminum Cylinder Block with Bulkhead Inserts and Aluminum Alloy Connecting Rod

2015-01-1238
The Multi Material Lightweight Vehicle (MMLV), developed by Magna International and Ford Motor Company, is a result of US Department of Energy project DE-EE0005574. The project demonstrated the lightweighting potential of a five-passenger sedan while maintaining vehicle performance and occupant safety. Prototype vehicles were manufactured and limited full-vehicle testing was conducted. The Mach-I vehicle design, comprised of commercially-available materials and production processes, achieved a 364 kg (23.5%) full-vehicle mass reduction. This resulted in environmental benefits and fuel economy improvements. A significant factor in the overall MMLV mass reduction was the decrease in the powertrain system weight from 340 kg (conventional) to 267 kg (MMLV). This enabled the application of a 1.0-liter three-cylinder engine as the main powerplant. By downsizing the engine, and by implementing material changes within the engine, the weight of the dressed engine was lowered by 29 kg.

MMT - A Further Evaluation

1977-02-01
770656
MMT (methylcyclopentadienyl manganese tricarbonyl) is an antiknock additive for the unleaded gasoline that is now required for cars equipped with catalytic converters. Because of its effectiveness, MMT is economically attractive compared with achieving antiknock quality by refinery processing. This paper updates an earlier SAE paper. Whereas the earlier paper evaluated all aspects of MMT use as an antiknock, this paper is primarily limited to analysis of the possible effects of MMT on exhaust emissions, catalyst plugging, and spark plug life. The results of recent tests and a report on a fleet test currently in progress are included.

MMT Effects on Gasoline Vehicles: A Literature Review

2016-03-14
2016-01-9073
Methylcyclopentadienyl manganese tricarbonyl (MMT) is an octane-boosting gasoline additive that has been used for over 50 years. This usage has been controversial; particularly in modern gasoline vehicles equipped with advanced emissions control systems. There is concern that extended use of MMT will lead to build-up of Mn-containing deposits on engine and emissions system components, thereby adversely affecting vehicle emissions performance and durability. This paper provides a comprehensive review of the literature regarding the effects of MMT on gasoline vehicles, with an emphasis on modern, Tier 2 vehicles. Numerous test programs have been conducted - including wide ranges of vehicle model years, technology types, and testing conditions. The reported MMT effects over this body of literature are not consistent.

MMT Plugging of Oxidation Catalysts on Ceramic and Metal Supports During Engine Dyno Studies of Catalyst Durability

1978-02-01
780005
DURING ENGINE DYNO durability testing of oxidation catalysts, manganese deposition on the catalyst hot faces sufficient to affect catalyst performance for HC and CO conversions was observed. The severity of the problem is related to the MMT level in the fuel, the cell density of the catalyst's monolithic support, and engine aging time. The nature of manganese deposition in these studies and how it affects catalyst performance is explored. Apart from the MMT phenomenon, comparative studies of oxidation catalysts on conventional ceramic and high cell density, thin-wall metallic supports indicate that the latter offer significantly improved HC conversion durability.

MMW Radar Target Classification Based on Machine Learning and Ensemble Learning

2022-01-7105
Although the video-based vehicle detection technology has the merit of low-cost, there are two obvious shortages: one is that the recognition effect is greatly affected by the weather and ambient lighting, and the other is that the amount of video data is large that may lead to the extra processing time. Compared with video-based and lidar-based technologies, millimeter-wave radar has some unique advantages in vehicle detection:(1) Sending and receiving signals are not affected by weather and illumination, and can perform all-weather measurements; (2) The cost is much lower than lidar, that is suitable for popularization; (3) The data processing and power consumption are superior to the vehicle detection system based on video processing. Therefore, this paper chooses FMCW-based millimeter-wave radar to build a vehicle detection system at an intersection.
