Engine Exhaust Controls The engine exhaust emission ... - Honda

Engine Exhaust Controls The engine exhaust emission control systems are designed to control combustion during idle, acceleration, cruise, and deceleration. These systems are entirely separate from the crankcase and evaporative emission control systems described previously. PGM-FI System The PGM-FI system consists of three independent subsystems; Air Intake, Electronic Control and Fuel Control, thus allowing more accurate control of air/fuel ratios under all operating conditions. The Electronic Control Unit (ECU) detects the amount of air drawn into the cylinders and determines the amount of fuel to be injected to provide the optimum air/fuel ratio for all engine needs. Ignition Timing Control System This system automatically controls the ignition timing to reduce the amount of HC and NOx. Exhaust Gas Recirculation (EGR) The EGR system is designed to control the formation of oxides of nitrogen (NOx) caused when fuel mixture burns at high temperature. It works by recirculating exhaust gas through the EGR valve and intake manifold into the combustion chambers where it reduces peak temperature by diluting the air/fuel mixture. Catalytic Converter The catalyst is used to convert hydrocarbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOx) in the exhaust gas to carbon dioxide (CO 2 ), dinitrogen (N2) and water vapor.

Nutrient Solution Formulation for Hydroponic - EDIS - University of ...

Nutrient Solution Formulation for Hydroponic (Perlite, Rockwool, NFT) Tomatoes in Florida1 George J. Hochmuth and Robert C. Hochmuth2 Plants require 16 elements for growth and these nutrients can be supplied from air, water, and fertilizers. The 16 elements are carbon (C), hydrogen (H), oxygen (O), phosphorus (P), potassium (K), nitrogen (N), sulfur (S), calcium (Ca), iron (Fe), magnesium (Mg), boron (B), manganese (Mn), copper (Cu), zinc (Zn), molybdenum (Mo), and chlorine (Cl). The key to successful management of a fertilizer program is to ensure adequate concentrations of all nutrients throughout the life cycle of the crop. Inadequate or excessive amounts of any nutrient result in poor crop performance. Excessive amounts can be especially troublesome since they can damage the crop, waste money and fertilizer resources, and pollute the environment when fertilizer is released during flushing of the nutrient delivery system. problem comes early in the season when plants become too vegetative (bullish) from too much N. The bullish growth distorts the leaves and stems, causing cracks and grooves in the stems. These openings are excellent entry ports for decay-causing organisms such as soft rot. Bullish plants usually produce misshapen fruits often with significant amounts of blossom-end rot and cat-facing. Keeping the N level low (60 to 70 parts per million) early in the season helps eliminate bullishness. For Florida greenhouse vegetable producers, management focuses on all nutrients except for C, H, and O. The latter three elements are usually supplied in adequate amounts from air and water. Growers in northern climates, where greenhouses are not ventilated in the winter, see benefits from additions of C from carbon dioxide (CO2). Increased yields in Florida from additions of CO2 are unlikely due to the need for frequent ventilation. Nutrient management programs should begin with an understanding of the nutrient solution concentrations in parts per million (ppm) for the various nutrients required by tomato plants. By managing the concentrations of individual nutrients, growers can control the growth and yield of the crop. Table 1 presents the fertilizer recommendations for tomatoes for the various growth stages during the season in Florida. These recommendations are applicable to all types of production systems (perlite, rockwool, and NFT) in which healthy roots are maintained, and are a suitable base when determining a nutrient solution plan for cucumbers and peppers. However, cucumbers will need more N early in the season than tomato.

Customer Frequently Asked Questions - Techinfo Toyota

Safety Recall D0H (D1H) - Preliminary Notice Certain 2010 Model Year Prius Vehicles Brake Booster Pump Assembly (Accumulator) Customer Frequently Asked Questions Published Early June, 2013 We at Toyota care greatly about your safety while we prepare the remedy for this condition. We are providing the following information to keep you informed of the recall details. Please check back frequently as this document will be updated. Q1: A1: What is the condition? The subject vehicles are equipped with brake pressure accumulators consisting of a metal plunger containing brake fluid encased in a metal housing. The plunger is designed with metal pleated bellows to allow for motion. Nitrogen gas is sealed between the plunger and housing. There is a possibility that a fatigue crack could develop in the bellows due to the vertical vibration of the plunger while driving. If this occurs, nitrogen gas could leak into the brake fluid and gradually cause the brake pedal stroke to become longer, resulting in decreased hydraulic pressure. Under certain circumstances, this condition could affect stopping distance and increase the risk of a crash. Q1a: A1a: Q1b: A1b: Q2: A2: What is the Brake Pressure Accumulator? Brake fluid is discharged by the Brake Booster Pump and passes through a check valve where it is then stored in the accumulator. The brake fluid that is stored in the accumulator provides the hydraulic pressure that is needed for brake operation. What is the cause of the condition? The cause of this condition is insufficient strength of components inside the brake pressure accumulator. Are there any warnings that this condition exists? Yes. You may notice a squeak from the engine compartment during brake application. Additionally, the brake pedal may have a longer stroke and/or spongy feeling.
