Malakas ba sa gas pag lagi nag start engine?

[danegoesonline]

Question guys.
1. Malakas ba konsumo sa gas everytime we start the engine?
2. Mas okay bang wag patayin ang makina kung mag idle ng 30 minutes?

Guys thank u sa mga sasagot

No. Mas malakas sa gas mag-idle ng matagal kaysa magstart ng makina.

The breakeven point is roughly 10 seconds. Yes, just 10 seconds. If you'll be idle for more than 10 seconds, better to just turn off your car.

Of course, don't shut off your car whenever you're stopped at an intersection. Aside from being a nuisance on the road, you also can't run your aircon properly with the engine off.

kung mag isa ka lang naman and mag idle ka nang 30 mins.. park properly.. and shut off the engine.. and get out of the car..

ngayon kung may sakay kang mga kids.. ibang usapan na yan..

30 mins is a long time to idle. Kung enclosed space delikado, and nakaka suffocate din ang exhaust. I don't even reach operating temps pag nag a-attempt ako magpainit sa garahe namen, dahil yung amoy.

I dont blame you these days, mainit din kasi talaga. I usually go to Starbucks or 7-11 parking pag meron.

this happens to me every sunday sa Promenade Greenhills pag nagcchurch kami every Sunday. Sobrang dami lagi ng sasakyan sa parking at sa pila palang papunta ng parking i spend 30-40 minutes na naka-idle lang. no wonder, malakas konsumo ng gas ko last few weeks

Thank you Jut ... this is something I've always wondered about ... anyone know how much cost of gas a vehicle actually consumes when idling with aircon on for an hour? ... say for a 2.5 diesel engine and a 2.0 gas engine ...

And you'll also wear out your starter and car battery earlier ...

Despite having unli-gas, I always shut off my engine whenever parked.

Pag mainit na, baba ng kotse and tambay somewhere.

Nasasayangan talaga ko mag-idle, really bad for FC.

kaya nga sir *jut703, nakakapanghinayang pero i don't have a choice naman...pag bumaba ako or nagpatay ako ng makina habang nasa pila papasok ng parking area, medyo hassle at baka isipin ng tao may oto ako pero walang pang-gas...hahaha! kidding aside, i usually get a 14-15 KMS/L sa byahe ko from Novaliches/Caloocan to Promenade on a Sunday morning tapos pagpasok ko sa parking at nakapagpark na, 9-10 KMS/L nalang. hinigop na lahat ni idle time sa parking...quotang kota talaga ako...hahaha!

Then don't shut off your engine. It doesn't really matter if you're worried about fuel consumption really. It's not a big deal. It's in impractical na dapat 10 seconds lang naka idle.

Kung kailangan mo talaga mag idle ng matagal then go ahead. You bought hay car for your convenience and not the other way around.

kung libre gas.. aba eh kahit ilang oras pa yan.. ok lang..

[glenn manikis]

Negligible lang ang Fuel during startup, 1-2secs. Lang naman... mas matipid pa din kung turn off mo engine

... and also not good for the environment ... idling only whenever there are short distance errands since it's not good for a vehicle to be doing too much short distance driving ...

Dahilan lang Car Manufacturers yan para mas mabilis mag wear yung engine kakastart. Saka lang nagkaka metal to metal contact sa bearing yung mga camshaft, crankshaft at connecting rod during start-up and shutdown. Pinakamalaking wear ng engine ay during start-up pagkatapos ng change oil & oil filter. Pag inalis filter babalik sa oil pan yung langis na nasa pick-up tube. If 1,000 RPM startup, 16 revolution per second.

Mas madaming fuel iniinject diesel kesa gasolina dahil walang throttle body diesel (except old Mbenz). Ang diesel puno palagi piston sa intake stroke. Pag gasolina konti lang papasok na air kasi na close almost yung throttle body sa idle. Kaya lang naman mabilis maubos gasolina dahil sa pesteng EVAPORATIVE EMISSION. Sa halip na icondensed yung mga nagiging vapor pinapasunog sa catalytic converter w/o producing power. Kung wala sa loob ng fuel tank ang fuel pump napakatipid ng gasolina. Here's a good explanation from Ford about EVAP.

"In relatively recent years, emissions regulations have become so stringent that the government is now regulating the emissions output that gasoline vehicles are allowed to produce even when the engine is not running! This is referred
to as “evaporative emissions” and results from unburned hydrocarbons (raw fuel) emitting into the atmosphere from the fuel tank, fuel lines, injector leakage, intake manifold, etc. when the engine is shut off. This is the fundamental purpose of the charcoal canister (and hydrocarbon trap in the air-box on many vehicles) and is also the reason that Ford switched to the Returnless Fuel Systems (RFS) found in production vehicles today. These systems have only a fuel supply line from the tank to the engine, with no return line. The primary reason for these systems is that evaporative emissions increase as the temperature of the fuel in the tank increases. On a conventional return system, the fuel is sent to the engine through the supply line, and the excess is returned (via the mechanical fuel pressure regulator) to the tank through the return line. Since the engine is hot, this process heats up the fuel and thus increases evaporative emissions. To combat this, the returnless fuel systems were invented"

Displacement lang yung 2.0, sukat lang ng bore & stroke ng lahat ng cylinder. Depende sa Horsepower ang size or flow rate Fuel Injector.
185hp 2.4 4 cylinder Inline = Fuel Injector 28lbs/hr (estimated)
210hp 4.2 V6 = Fuel Injector 21lbs/hr
220hp 4.6 V8 = Fuel Injector 19lbs/hr
235hp 5.4 V8 = Fuel Injector 19lbs/hr

Mas matipid ang Return Type Fuel System kesa Returnless pag idling basta full tank. Pag below 85% lang kasi gumagana EVAP pag return type. Di pati nakakapag purge EVAP sa idle pag return type. Pag nag purge sa idle EVAP mag stall engine. Pag returnless palaging nag pu-purge EVAP kahit naka idle lang. Mas matipid sa gasolina pag SUV pag return type. Naka balagbag kasi yung Fuel tank at malapit sa muffler pag kotse. Lahat ng diesel Fuel Injected pero di naman lahat nasa loob ng fuel tank. Napakalaking kalokohan ilagay sa loob ng fuel tank yung fuel pump pag gasolina kasi napakababa ng boiling point.

Marketing slogan lang yung "Environment Friendly". Basta narinig mo yung salitang yon ibig sabihin masakit sa bulsa dahil malaki nagastos sa ads at promotion. Best example yung Ethanol. Pano magiging environment friendly yon mababa yung mileage. Mas madami kang kailangan sunugin. Dagdag pa sa traffic yung mga tanker na truck sa polusyon para itransport yung fuel. Magagato kasi pipeline dahil conductive ethanol. Ang pinaka masama pa napaka hygroscopic kaya malakas sumipsip ng water vapor from air. Pati gasolina may expiration na rin.

hindi po ,,mas malakas ang kunsumo ng gas pg nka idle kayu..gas kc yan basta na andar makina nyo tloytuloy na konsumo nun,pg diesel po ata hindi mastipid pa pg naka idle

Guys thank u sa mga sasagot

hindi po,,. malakas tlaga sa gas pg nka idle lang.sa palagay ko po sa diesel un effective,mas ok pa naka idle kysa mag start ng engine.

Punuin mo kasi fuel tank mo. Matakaw talaga sa gas pag kokonti laman ng fuel tank. Malakas talaga mga new model sa fuel pag naka idle kasi gumagana palagi EVAP.

The 30minutes idle scenario is practical only in the parking lot. In other words you dont stay idle for 30minutes in an intersection or on the road

And its always more frugal to shut your engine if you dont intend to move for a long period of time

Fuel drives a combustion engine and it doesnt matter if its gas or diesel. In the absence of fuel the engine stalls just like when a fuel tank gets dry.

Sa 01 E150 4.6 V8 30 gallon fuel tank return type fuel system. Basta puno yung fuel tank 1 hour idling di pa aabot ng 1liter/hr. Basta yan dala ko inaabot ako 2-3hrs idling. 3 yung fuel line from fuel tank supply, return at evap. Saka lang gumagana EVAP pag 85% na lang fuel level. Basta gumana na yung pesteng EVAP na yan parang may butas fuel tank sa lakas ng fuel consumption. Kaya nga madami noon ang naniniwala na matipid pag konti laman ng fuel tank kasi pag below 15% na lang fuel di na gumagana EVAP.

Pag 2012 CRV gamit ko di ako makapag idling kasi napakatakaw sa idle. Malakas pa lumamon ng fuel kesa sa F150 ko na 4.2 V6 OHV. FACT: Mas tipd sa Fuel consumption ang overhead cam kesa overhead valve engine. Mas matakaw pa sa 5.4 SOHC V8 ang 4.2 V6 na OHV. Ang advantage ng OHV over OHC are reliability. Masarap pati idrive OHV kasi malakas Torque.


Kalokohan yung computation ng fuel consumption. Hindi naman Air ang kailangan para masunog ang fuel kundi oxygen. Ilan % lang ba ang oxygen sa air? Based on scantool 1.3-1.5 liters / hr daw fuel consumption. Pero pag pinakargahan ko pahirapan pa masalinan ng 3 liters.

Scam yang pesteng EVAPORATIVE EMISSIONS na yan. Clean the air by burning more Fuel without producing power. Isn't it stupid? Sa halip na I condensed yung mga nagiging fuel vapor pinapasunog sa catalytic converter without producing power. Kaya nga ginawang electronic yung throttle body kahit marami na naaksidente dahil sa SUA para makapag purge ng fuel vapor sa idle. Pag manual kasi throttle body pag nag purge yung EVAP sa idle mag stall yung engine. Saka lang nakakapag purge yung EVAP noon kasabay ng EGR pag mataas RPM.

Kaya napakamahal ng fuel dahil sa pesteng media na reliable source of wrong information. Sa Venezuela gasoline only cost $0.06 USD per US gallon. Pang 10th place lang Venezuela sa world's largest oil producing country worldwide. Tingnan mo kung anong country yung nasa 3rd place today. Sila yung 1st place noong 2014. Pano ba naman hindi tataas yung price ng oil yung 3rd largest oil producing country nag impoport ng oil sa halip na nag eexport. Compare mo price ng diesel at gasolina sa US at sa pinas, Sa US self service pag pag pump ng fuel. Natawa nga sa akin yung cashier kasi tinanong ko kung pano mag pump ng fuel nung nag punta ako ng US. From what cave, mountain or stone aged country daw ako galing at hindi ako marunong mag pump ng fuel in english. Sabi ko, Sorry I'm came from 3rd world country. Gas station employs people who pumps fuel for me, check engine oil, coolant, tire pressure and cleans my windshiled at no extra cost.

FACT: AViation Fuel aka AVGAS is still leaded until today. May unleaded din Peteon Blaze 100 octane pero requires more maintenance at mas mataas risk ng engine failure. Madumi sunugin unleaded at mahina hatak. Yung 2 seater na Cessna 152 ang average fuel consumption ay 6 gallons per hour.
